SAP HANA is an in-memory database which also provides HANA Modeling, Data

Provisioning, and BI reporting features in a single application. SAP HANA is mostly used

as a Data Warehouse for many organizations with Transaction system. SAP is providing HANA as a backend database for various different ERP and CRM based applications.

Following are a few common HANA based modules:

S/4 HANA (S/4 HANA Finance and Logistics)

SAP Business One

SAP Fiori

SAP HANA Data Modeling helps the user to model the application data and perform

database functions such as creating schemas, tables, and views at run time. HANA data

models are stored in HANA Repository and objects are activated at run time.

This is SAP site link for HANA Product details that shares all key features HANA provides -https://www.sap.com/products/hana.html

According to SAP - “Deployable on premise or in the cloud, SAP HANA is an in-memory

data platform that lets you accelerate business processes, deliver more business

intelligence, and simplify your IT environment. By providing the foundation for all your

data needs, SAP HANA removes the burden of maintaining separate legacy systems and

siloed data, so you can run live and make better business decisions in the new digital economy.”

BI development is always a challenge for organizations with massive amount of historical

data. Traditional databases or DW systems - SQL Server, BW or Oracle - doesn’t support

live reporting, as they are not capable of running the transaction system and Data

Warehouse on the same system. In many organizations, transactional system and Data

warehouse are kept separate, as running complex OLAP queries affect the performance of

the systems significantly. ETL processes are used to perform extraction, transformation,

and data load from SAP ECC to Data Warehouse.

When large number of concurrent OLTP transactions are made along with OLAP queries,

there is a possibility of the system getting crashed. SAP HANA supports real-time data

replication from the transaction system using SLT method, which is a trigger-based approach of data replication.

SAP HANA is an in-memory database, hence the data read is 1 million times faster as

compared to traditional systems. Complex OLAP queries in a Business Intelligence report

takes less time to run when DW system contains huge amount of historical data. HANA

supports all aggregations on fly, and hence, there is no need to save aggregated table in

the database. Due to different compression algorithms and column-based storage of table,

HANA database requires less space to store more data as compared with other RDBMS systems.

SAP provides BusinessObjects as BI reporting and dashboard tool, used by many

organizations who have SAP ERP implemented as the transaction system. SAP

BusinessObjects consist of multiple tools for Business Intelligence reporting and dashboard:

Web Intelligence

Dashboard Designer (Earlier known as Xcelsius)

Universe Designer (For Semantic Layer)

SAP Crystal Reports

SAP Lumira

SAP Design Studio

BusinessObjects Explorer

Analysis for OLAP

All these tools are closely integrated with SAP BW and SAP HANA and support all data

modeling and ETL features of SAP system. Web Intelligence is used for detailed reporting

and uses Query Panel and Universe Designer as the semantic layer to connect to non-SAP

data sources. Dashboard Designer is the dashboard tool which provides lot of predefined templates for creating static and dynamic charts.

Universe Designer (UDT/IDT) is a tool to build the semantic layer for non-SAP data

sources as well as to build data models for HANA database objects. Different features such

as parameters, filters, creating/deleting objects, business layer views, predefined queries

for testing, aggregations and variable mapping can be defined using the semantic layer.

When the semantic layer is finalized, it can be published to BO server repository and can be used in different Webi reports and Dashboards.

SAP Crystal Reports is used for pixel perfect reporting where users want to take printout of sales invoices, bills, sales orders, etc.

SAP Lumira is one of the emerging data visualization tools that provide the users with an

option of ad-hoc dashboarding feature.

SAP Design Studio is also an advanced level dashboard tool and supports server side programming to create interactive dashboards for customers.

SAP BusinessObjects Explorer is a self-service BI tool to create dashboard views and data visualizations, and share them with other users in the team.

Analysis for OLAP is also a self-service multidimensional analysis tool and is suitable for reporting on SAP BW and SAP HANA.

The above picture shows all BI tools with solid lines, which can be directly connected and

integrated with SAP HANA using an OLAP connection. The tools that need a relational connection using IDT to connect to HANA are shown with dotted lines.

SAP BusinessObjects was an individual product earlier. In 2008, SAP acquired this product

and added it as one of the key tools for SAP BI reporting.

Following is the version history of SAP BO tool in reverse chronology:

SAP Business Objects Business Intelligence 4.2 Service Pack 04 (Release Date, 2017)

SAP Business Objects Business Intelligence 4.2 Service Pack 03 (Released Date,

September 2016)

SAP BusinessObjects Business Intelligence 4.2 (Release Date, 18-May-2016)

SAP BusinessObjects Business Intelligence 4.1 (Release Date, 23- Nov-2013)

SAP BusinessObjects Business Intelligence 4.0 (Release Date, 16-Sep-2011)

SAP Business Objects XI R3.0

SAP Business Objects XI R3.1

Business Objects XI R1

Business Objects XI R2

Business Objects 6.x

Few of these tools can be directly accessed using a web interface known as BI Launchpad.

BI Launchpad is a Java or HTML based interface of BusinessObjects tool to perform

analytical reporting and data analysis. You can set the preference for your BI Launchpad that determines, which tool interface is launched via Launchpad.

Using Web or Internet Application to access Webi interface via BI Launchpad, you can

perform the following tasks −

Create, edit, and refresh all the reports in Web Intelligence.

Create and edit all the queries in no data source (Universes) but not BEx queries in Web application.

BI Launchpad has the following important tabs −

Home − Displays the recent messages, alerts, documents, and applications that

can be run.

Documents − Displays the available documents and folders, making it easier to

view, organize, and manage the documents.

Any open Document − Displays each open document.

You can use the Application tab to start an application including Web Intelligence. You can use the Preference tab to define BI Launchpad preferences.

To get the BI Launchpad details and user credentials you can reach the BO Administrator.

BI Launchpad has the following URL http://BOSERVER:8080/BOE/BI. To login to BI

Launchpad, open the web browser and enter the Launchpad URL provided by your administrator. The following screen pops up.

http://boserver:8080/BOE/BI

In SAP BusinessObjects, different tool connects to HANA using different type of

connections. Few of the tools connect to the Database layer - Tables, Views, etc. using a

Relational connection to HANA database, however, other tools directly connect to Data Modeling layer using an OLAP connection.

An OLAP connection can be created in the Central Management Console (CMC) or a Relational connection and OLAP connection can also be defined in the Universe Designer.

Relational Connection

A Relational connection is used to connect to the database layer in HANA. You can connect

to database objects - tables, views, and design Data Foundation layer in the Information Design tool. You can also import tables and joins from the data source.

OLAP Connection

OLAP is a multidimensional connection that directly points to the business layer in a data

model. It allows you to connect to the multidimensional schema directly and later, they

can be used with SAP BusinessObjects reporting tools.

BICS Client

To connect to SAP NetWeaver BW, you can use SAP BICS client middleware to provide

access to BEx query. Connections in IDT can be locally saved or they can be secured and

published in a central repository.

Local connections are saved as .cnx files and they can be accessed by any user who is

running IDT. Once you publish the connection to the repository, they are changed to a secured connection.

A secured connection is published into the repository and saved in the Connection folder.

You can also create secured connections using Insert Relational and Insert OLAP

connection commands from the repository resource view.

3. SAP HANA BI Development ─ Different BO Tools Connection to HANA


7

Let us see how to create a Relational connection that can be used to connect to HANA database layer to design Data Foundation layer for BOBJ reporting in a Universe.

Navigate to Information Design Tool -> Click New -> Project -> Enter the Project Name -> Finish. Right-click the Project name -> New -> Relational Connection.

In the next window, enter the name of Relational connection -> Click the Next button.

4. SAP HANA BI Development ─ Creating a Relational Connection


8

To set up a connection to HANA database, select SAP HANA database 1.0 from the driver

selection screen. In the following snapshot, we have selected SAP HANA -> JDBC Drivers -> Next.

Note that to connect to HANA database, you should have the following information:

Host Name

Instance Number

User Name

Password

You can also select from different authentication modes such as LDAP or any other mode,

which is configured for HANA system login. Click the Next button.


9

In the next window, you will be prompted to enter Connection Parameters - Connection

Pool Mode, Pool Timeout, Array Fetch Size, Array Bind Size, Login Tmeout, etc. Once you pass this information, click the Finish button.

This will create a Relational connection to source HANA database and it can be used to

connect to Database layer objects for reporting. You can see the following information on

the Connection parameter screen:

General

Login Parameter

Configuration Parameter

You can also edit any of the parameter value by the click of the edit button. When this

connection is used in the Universe Designer, this will point to all database objects in HANA

database. You can import tables, views from HANA database to build a data foundation

layer of a Universe. To test the connection, click the Test Connection and you will get a message that the Connection is successful.


10

To publish this connection to BO repository so that it can be used by any tool, right-click

the connection name and select Publish Connection to a Repository. This will create a new

object in the project tab with .cns extension.

.cns - Secured Repository connection

.cnx-local unsecured - If you use this connection, it will not allow you to publish anything to the repository.

Note: In SAP BusinessObjects, most of the tools support Universe as the data source for

reporting. Using a Relational connection, you can connect to any HANA database system,

and import tables and views for Data Foundation Layer. Once .dfx is defined, it is required

to develop a Business Layer on the top of this layer. When the Universe is published to BO server repository, it can be used by any BOBJ tool for reporting purpose.


11

An OLAP connection is used to connect to HANA Information view or a data model and to directly import all the business objects defined in the Business Layer for reporting.

To create a new OLAP connection, right-click the Project name -> New -> OLAP Connection.

In the next window, enter the Connection name, Description (Optional) and click Next.

Note: You point an OLAP connection to a specific cube or to complete HANA repository.

When this connection is used in any BO Reporting tool, you can directly import all objects

in HANA Modeling view or can also view all published information views in the repository

and select any of them for reporting.

Next, select an OLAP middleware driver. It shows a list of all available OLAP data sources. You can select any OLAP data source as per requirement.

Note: You don’t need to create a Data Foundation, as an OLAP directly hits the Business

Layer. You can define dimensions, measures, and other properties at the Business Layer.

5. SAP HANA BI Development ─ Creating an OLAP Connection


12

Select the suitable middleware driver to connect to OLAP data source and click Next. To connect to HANA views, select SAP HANA -> SAP HANA Client.

To connect to HANA system, you need the following information:

Server Name

Instance Number

Authentication Details


13

When you fill the above details and click the Next button, you have an option asking if you want this connection to point to a specific cube or to all cubes in HANA repository.

Once this option is selected, click the Finish button at the bottom of the screen.

Now, you need to publish the connection to the Repository. Right-click Connection ->

Publish the Connection to the Repository.

When a new connection is created using Information Design tool, you have the following connection parameters that can be defined:

Connection Pool Mode: This is used to keep the connection active.

Pool Timeout: When you set the Connection Pool Mode to Keep the connection

active for, it is the length of time in minutes to keep the connection open.

Array Fetch Size: This tells the maximum number of rows that can be fetched

from the database.


14

Example

Let us consider an example. You enter a value of 25 and your query returns 150 rows. Hence, it will be fetched with 6 fetches of 25 rows each.

Array Bind Size: This field is not required for designing the Universe in IDT.

Login Timeout: It determines the minutes a connection attempts timeout and an error message is displayed.

There are various custom parameters that can also be defined such as ConnectInit, Hint.


15

SAP HANA Modeling is one of the key capabilities of HANA system. This allows to create

multidimensional objects on top of HANA database objects to meet the business

requirements for reporting. You can implement complex business logic using HANA information models to create a meaningful report for analysis.

Features of HANA Modeling

SAP HANA Modeling is one of the key concepts in HANA BI reporting.

Using HANA Modeling, you can create complex data models as per business

requirement to provide multiple views of transactional data stored in physical tables

of HANA database.

SAP HANA Modeling can only be done for column-based storage tables.

HANA Modeling views can be used directly by SAP BusinessObjects reporting tools

such as Crystal Reports or Lumira using an OALP or HTTP connection.

HANA supports different types of Modeling views such as - Attribute view is used

to model characteristics, Analytic view is used to implement Star schema and

Calculation view is used to implement complex logics, which are not possible with

other type of views (Galaxy schema).

SAP HANA Modeling views can also be directly connected to third party tools such

as MS Excel using HANA MDX Provider.

SAP HANA Modeling supports various features of Business Layer - Creating new calculated columns, new measures, input parameters, hierarchies, etc.

SAP HANA provides following three types of Information Views:

Attribute View

Analytic View

Calculation View

All HANA Modeling objects are stored in HANA Repository and it can be directly accessed

using any BI tool via proper authentication. When these objects are imported in any of the

reporting tools using an OLAP or HTTP connection, it also imports all the custom properties of that model.

6. SAP HANA BI Development ─ HANA Modeling Views


16

SAP HANA suite also offers basic BI reporting functionalities, where you can create interactive charts using data in HANA models.

Like other BI reporting tools, you can add dimension and measure values to Label and Value axis. HANA provides the following options for BI analysis:

Analysis: This tab is used to add different dimension and measure values to

different label axis. Filters can be applied as per business requirement.

Distinct Values: This tab is used to see distinct values in data analysis for each of

dimension.

Raw Data: This tab shows all raw data coming from data model as per Business

Layer parameters.

In a BI report, you can select from the following options: Chart, Table, Grid, or HTML.


17

In SAP HANA, input parameters are used to filter the data by passing an input from the

user and to perform additional calculations at run time. The data is fetched based on the

input value, when a view is executed.

Example

Consider a scenario where an Input parameter is applied on the “Sold_Qty”, i.e. when the

Sold_Qty is greater than 20, then there is 10% discount on Total_Price. Otherwise, it remains the same.

Input parameters are created in HANA Modeling views using SAP HANA Studio. When these

views are used in any BO reporting tool and the report is refreshed, users are prompted

to pass an input value for a particular field. To create a new parameter, navigate to the Semantic section of HANA Modeling view.

Navigate to Parameters/Variables tab in the Semantic layer and click the “+” sign. Select Create Input Parameter as shown in the following screenshot.

7. SAP HANA BI Development ─ Input Parameters in HANA


18

This will open a new dialog box. Enter the technical name and description of the Input parameter. Select the Input Parameter type from the dropdown list.

We have the following input parameter types in HANA:

Direct: Using this parameter type, you can pass any value for the parameter.

Column: This parameter type allows you to select any value from the list of distinct

values available in a column in HANA view.

Derived from table: It is also possible to create dynamic values in a table and allows

you to select any of available value from the list.

Static List: It is also possible to create a static list of values and provide an input

during execution.

Note: You can also select the checkbox to make an Input Parameter a mandatory option.


19

You can select the data type of the input value, so that the system only accepts allowed

value type for this field. This option varies as per parameter type. Following data type options are available:

Currency

Unit of Measure

Date

You can also pass Input parameter using SQL query. To view SQL query, navigate to the

Data Preview tab of HANA Modeling view. Input parameter using SQL is passed using

“PLACEHOLDER”.

Next, click the “Show Log” and then double-click the message highlighted below. This will open a new window with the following SQL query.

('PLACEHOLDER' = ('$$ Sold_Qty $$', '20'))

WHERE ("REGION_NAME" IN ('NA') )

GROUP BY "NET_AMOUNT", “PROFIT”;


20

In SAP HANA, Attribute Views are used to model characteristics. They are used to join

Dimension tables or other Attribute Views. You can also copy a new Attribute View from

the already existing Attribute Views inside other Packages, but that doesn’t let you change the View Attributes.

Following are the key characteristics of HANA Attribute view.

Attribute Views are used in Analytical and Calculation Views for analysis to pass

the master data.

They are similar to characteristics in BM and contain the master data.

Attribute Views are used for performance optimization in large size Dimension

tables. You can limit the number of attributes in an Attribute View, which are

further used for reporting and analysis purpose.

Attribute Views are used to model the master data to give some context.

How to Create an Attribute View?

In SAP HANA, all modeling objects are created inside the package and stored in HANA

Repository. Choose the Package name under which you want to create an Attribute View. Right-click Package_Name -> Go to New -> Attribute View…

When you click Attribute View, a new window will open. Enter Attribute View name and description in this window and from the dropdown list, choose View Type and Sub-type.

8. SAP HANA BI Development ─ Using Attribute View


21

Following are the categories of Attribute View sub-type -

Standard

Time

Derived

If you want to copy an existing Attribute view, you can use the “Copy From” option. When

you click the “Copy From” option, it shows all other Attribute views that you can use to create a copy.

Time sub-type Attribute View is a special type of Attribute view that adds a Time Dimension

to Data Foundation. When you enter the Attribute name, type, and sub-type and click

Finish, it will open three work panes −

Scenario pane that has Data Foundation and Semantic Layer.

Details pane that shows the attribute of all tables added to Data Foundation and

joining between them.

Output pane where you can add attributes from the Detail pane to filter in the report.

You can add Objects to Data Foundation, by clicking the ‘+’ sign written next to Data

Foundation. You can add multiple Dimension Tables and Attribute Views in the Scenario

Pane and join them using a Primary Key.

When you click Add Objects “+” sign in Data Foundation, you will get a search bar from

where you can add Dimension tables and Attribute views to the Scenario Pane. Once Tables

or Attribute Views are added to Data Foundation, you can see all the columns on the right

side pane. They can be joined using a Primary Key in the Details Pane as shown in the

following screenshot.


22

Once the joining is complete, choose multiple attributes in the details pane, right-click and

Add to Output. All columns will be added to the Output pane. Now click the Activate option

and you will get a confirmation message in the job log.

Now you can right-click the Attribute View and go for Data Preview. Once you click Data

Preview, it will show all the attributes that has been added to the Output pane under Available Objects.


23

SAP HANA also provides reporting feature for data analysis. These Objects can be added

to Labels and Value axis by a right-click or by dragging the objects as shown in the following screenshot.


24

Analytic View is in the form of Star schema, wherein we join one Fact table to multiple

Dimension tables. Analytic views use real power of SAP HANA to perform complex

calculations and aggregate functions by joining tables in the form of Star schema and by executing Star schema queries.

Following are the key characteristics of SAP HANA Analytic View −

Analytic Views are used to perform complex calculations and Aggregate functions

such as Sum, Count, Min, Max, etc.

Analytic Views are designed to run Star schema queries.

Each Analytic View has one Fact table surrounded by multiple dimension tables.

Fact table contains a primary key for each Dim table and measures.

Analytic Views are similar to Info Objects and Info sets of SAP BW.

SAP BusinessObjects reporting tools can connect to Analytic view using an OLAP

connection for reporting and dashboard.

How to Create an Analytic View?

In SAP HANA, you can create an Analytic view to implement Star Schema queries. All these objects are created inside a Package and published to HANA Repository.

To create a new Analytic view, select the Package name under which you want to create

it. Right-click the Package -> Go to New Tab -> Analytic View. When you click an Analytic

View, a new window will open. Enter the View name and Description and from the dropdown list and choose the View Type and finally click Finish.

When you click Finish, you can see an Analytic View with Data Foundation and Star Join

option. To add tables to the Analytic view, click the Data Foundation to add Dimension and Fact tables. Click the Star Join to add Attribute Views.

9. SAP HANA BI Development ─ Using Analytic View


25

Add Dim and Fact tables to Data Foundation using “+” sign. In the following example, we

have added 3 dim tables to Data Foundation: DIM_CUSTOMER, DIM_PRODUCT,

DIM_REGION and 1 Fact table FCT_SALES to the Details Pane. A Join is applied to connect Dim tables to the Fact table using Primary Keys stored in the Fact table.

Select Attributes from Dim and Fact table to add to the Output pane as shown in the following screenshot. Change the data type of Facts, from the fact table to measures.


26

Navigate to the Semantic layer, select dimension and measures and click the data type if it is not picked by default. You can also use Auto-detection. Next, activate the View.

To activate the view, click the Arrow mark at the top (F8) button. Once you activate the

view and click Data Preview, all attributes and measures will be added under the list of

Available objects. Add Attributes to Labels Axis and Measure to Value axis for analysis purpose.


27

Calculation views are used to perform complex calculations, which are not possible with

Attribute or Analytic view. You can also use Attribute and Analytic views while designing

Calculation views.

Following are a few characteristics of Calculation Views −

Calculation Views are used to consume Analytic, Attribute, and other Calculation

Views.

There are two ways to create Calculation Views - Using SQL Editor or Graphical

option.

It has built-in Union, Join, Projection, and Aggregation nodes.

SAP BusinessObjects reporting tools can connect to Calculation view using an OLAP connection for reporting and dashboard.

How to Create a Calculation View?

Choose the Package name under which you want to create a Calculation View. Right-click

the Package -> Go to New -> Calculation View. When you click the Calculation View, a

new window will open.

Enter the view name, description and choose the view type as Calculation View, Sub-type

Standard or Time (this is a special kind of View, which adds time dimension). You can use two types of Calculation View − Graphical and SQL Script.

10. SAP HANA BI Development ─ Using Calculation View


28

Calculation view provides an option of using a Star Join or not to use a Star Join. Also, it has two different Data Categories:

Cube: When a user selects Cube as data category, the default node is Aggregation.

You can choose Star Join with Cube dimension.

Dimension: When a user selects Dimension as data category, the default node is

Projection.

Calculation View with Star Join

When you use Calculation view with Star Join, it does not allow base column tables,

Attribute Views, or Analytic views to add at data foundation. All Dimension tables must be

changed to Dimension Calculation views to be used in Star Join. All Fact tables can be added and can use default nodes in Calculation View.

Example

The following example shows how we can use Calculation View with Star Join.

You have four tables, two Dim tables, and two Fact tables. You have to find a list of all employees with their Joining date, Emp Name, empId, Salary, and Bonus.


29

Advantages of Using a Star Join

It simplifies the design process. You need not create Analytical views and Attribute

Views. Fact tables can be directly used as Projections.

3NF is possible with Star Join.

Calculation View Without Star Join

This allows the use of other Attribute views and Analytic views using different nodes

available in Calculation Join.

In the above screenshot, you can see two Analytic views - AN_Fact1 and AN_Fact2 - are

used using node Projection 1 and Projection 2 and then joined with the help of a Join node.


30

SAP HANA is an in-memory database that supports all the features of a conventional

database. You can perform all DDL, DML, and DCL statements on database objects. Users

can create new tables, views, functions, triggers, and all other database functions using HANA Studio front-end.

Tables in HANA database can be accessed from HANA Studio in Catalogue tab under Schemas. New tables can be created using the following two methods −

Using SQL editor

Using GUI option

All the database objects - tables, views, and other objects can be used to design a Universe

- Data Foundation layer and later to publish Business Layer to BO repository for BI reporting.

How to Access the SQL Editor?

In SAP HANA Studio, open SQL editor by selecting the Schema name and click the circled

option in the following screenshot. You can run all SQL queries in SQL editor, which are

required to perform conventional database functions. You can create new tables, views by

writing the CREATE command in the editor window or right-click the Schema name and write the following Create script.

Following is the Create table SQL command that can be used to create a column table in HANA database.

Create column Table Sample1 (

Cust_ID INTEGER,

Cust_NAME VARCHAR(10),

PRIMARY KEY (Cust_ID)

);

11. SAP HANA BI Development ─ Using Tables in HANA DB


31

To insert the data, run the Insert statement in SQL editor. “Sample” is the table name.

Insert into Sample Values (101,'Jon');

Insert into Sample Values (201,'Tina');

Insert into Sample Values (301,'Jacob’);

When the data is entered, you can see the data in this row-based table by going to Data Preview option. To see the data, right-click the table name -> Open Data Preview.

All the database objects in SAP HANA system are maintained in CATALOG folder in HANA Studio. Following are the key capabilities of SAP HANA database system:

You can use high performance in-memory database for processing complex

transactions and analytics. You can manage large database volumes in multitenant

database containers.

SAP HANA system combines OLAP and OLTP processing into a single in-memory

database. It removes the disk bottlenecks, offering groundbreaking performance.


32

Using SAP HANA in-memory database component, you can run advanced analytical

queries, which are complex in nature with high-speed transactions to get the

correct, up-to-date responses in a fraction of a second.

All the 2-dimensional objects exist in schemas in HANA database. Schemas are shown

under the Catalog folder in HANA Studio. When you expand any of the schema, you can see different Relational objects - functions, indexes, views, and synonyms inside it.

If you open SAP HANA cockpit using the following link, you can see different database functions in HANA system: https://best:4303/sap/hana/admin/cockpit

How to Create a View in HANA DB?

To create a view in one table, write the following SQL statement.

create view view_name as

select ARTICLE_ID,ARTICLE_LABEL,CATEGORY,SALE_PRICE from "AA_HANA11"."ARTICLE_LOOKUP";

https://best:4303/sap/hana/admin/cockpit


33

Dropping a View

You can drop a view using the Drop command, like we drop a table.

Drop view "AA_HANA11"."DEMO_TEST";


34

In older versions of SAP BusinessObjects (4.1 or earlier), the only option to connect Webi

with HANA is with the use of the Universe. The Universe is designed on top of HANA views

and then using Webi query panel, we can use objects in Webi report.

With the release of SAP BO 4.2, SAP provides multiple ways to connect Webi report to HANA

views. Following are the four ways to connect Web Intelligence to HANA Modeling views:

Using Universe on top of HANA Modeling Views

Direct Webi connection with HANA Modeling views

SAP HANA Online connectivity

Using Free-Hand SQL

Using Universe on Top of HANA Modeling Views

As mentioned earlier, we can develop HANA Views - Attribute, Analytic and Calculation

views - using HANA Studio. To create a Universe, you have to create a Relational

connection pointing to HANA DB schemas.

To create a new Relational connection, first start with a new project under Local Project

view. Open Information Design Tool -> Click New -> Project -> Enter the Project Name -> Finish. This will create a new Project under Local Projects window.

Next, right-click the Project name -> New -> Relational Connection.

12. SAP HANA BI Development ─ Connecting Webi to HANA


35

In the next window, enter Connection Name -> Enter the connection/resource name -> click Next.

You will be prompted to select a Middleware for connection. Select the middleware as per

data source. You can select SAP or non-SAP as data source and set up a relational connection to the database.

Here, we have selected SAP from the list -> SAP HANA database -> JDBC -> click Next.


36

In the next window, enter the Authentication mode, user name and password. Enter SAP HANA host name and Instance number, then click Next.

In the following window, define connection parameters such as - Time out, Array fetch size, Array Bind size, etc. Click Finish.

When you click the Finish button, this will create a new Relational Connection pointing to

SAP HANA database with .cnx file extension. You can click Test Connection. The lower part

of the Window tells you about connection parameters - Login parameters, configuration parameters, etc.


37

Click Test Connection -> Successful. You have to publish this connection to the Repository to make it available for use.

To publish this connection, right-click the connection name -> Publish connection to Repository -> Enter BO repository password -> Connect -> Finish -> Yes.

Now, create a Data Foundation using SAP HANA view. Right-click Connection name -> Select New -> Data Foundation.


38

Enter Resource Name and click Next. You can select Single source enabled or multi-source

enabled as the data foundation type. Select multisource-enabled and pass the authentication details after selecting the connection.

After you click Next, select _SYS_BIC schema node, where all HANA views and column

tables are stored. Add the required view from HANA to Data Foundation layer. You can

develop the Business Layer on top of this data foundation, and it can be published to BO server repository for reporting purposes.

Direct Webi Connection with HANA Modeling Views

This feature is added to SAP BO 4.2 recently which allows direct connection to HANA

Modeling views using an OLAP connection. When you connect to HANA Repository using

an OLAP connection, you can connect to all Packages created in HANA system. You can select any of the package -> Navigate to HANA views stored in the package.

Once these steps are performed, all dimensions and measures are added to the Query

Panel in Webi. The developer can select any of the result objects from the list of available objects and click the run query to add those Webi report.


39

SAP HANA Online Connectivity

In SAP BO 4.2, there is an option of using HANA Online Connection that allows Webi client

to connect directly to HANA views. There is no need to build a Webi query for using HANA Online connection option.

This option lists Relational connection only and when the connection is selected, it shows

all the packages and corresponding views. When HANA view is selected, it directly connects to Webi Reporting Layer. There is no use of Query panel in this scenario.


40

Using Free-Hand SQL

In SAP BO 4.2, a new option – free-hand SQL - is introduced in Web Intelligence that

connects directly to HANA views. When you connect using a Web Intelligence tool that

connects using Free-hand SQL option, a tool lists down all HANA Relational connection

from BOBJ server. When you select a Relational connection, a tool provides a query script editor to write the query.

To use Free-Hand SQL option, select a new Webi document, and in the data source list

select Free-Hand SQL option.

Once you select this option, a query editor opens up. You can write a SELECT query to

form Webi Query for reporting. On the right side, you have a Run Query option and the list of available objects in Webi tool.


41

To create a Universe in IDT, go to Start -> All Programs -> SAP Business Intelligence -> SAP Business Objects BI Platform 4 Client Tool.

In Information Design Tool, you have to create a New Project. Go to File -> New -> Project.

Enter the Project Name and Click Finish.

Once the project is created, next is to create an OLAP or Relational connection to connect

to a data source - SAP HANA in this case. A Relational connection is used to connect to

the Database layer to import tables and joins. An OLAP connection is used to connect to the multidimensional model like an Information View in SAP HANA.

You have to publish this connection to the Repository to make it available for use. Right-

click the connection name -> Publish the connection to the Repository -> Enter BO repository password -> Click Connect -> Finish -> Yes.

The next step is to create a Data Foundation Layer on this secure connection. Right-click

.cns Repository connection -> Click New Data Foundation.

Enter Resource Name and click Finish. It will show you a list of all available schemas in

the database. You can add Tables and Joins from Schema to Data Foundation layer. This

can be done by dragging the table or by a double-click. Apply the joins on Dimension and

Fact tables to create a logical schema.


43

To define a Join, double-click the Join between tables. It will show you both the tables.

You can select from different Joins as per data requirement and click Detect Cardinality to define the cardinality - 1:1, 1:n, n:n.

Next is to create a Business Layer on the Data Foundation. Click the Save All icon at the

top of the screen. Then, right-click Data foundation .dfx -> New Business Layer. Enter

Resource Name -> (Generating Business Layer for Data Foundation) Finish. It will add Business Layer .blx under the Local Project.

It will show a list of all dimensions and measures under Data Foundation. Define dimensions, measures, aggregation, etc.

To define an Aggregation, select from the Projection Function. You can hide few objects in

the report if you want using the dropdown next to measures and dimension. You can select Hidden for a particular object.

In the Universe Designer, you can add a Prompt in Data Foundation and they are directly

inherited to the Business Layer on top of Data foundation. Note: If there is a need to edit

a Prompt, it can’t be done in the Business Layer. You have to open Data Foundation for the same.

To insert a Prompt, click parameters and List of Values (LOVs) tab in the browsing pane -

> Click Insert Parameter icon.

Using LOVs

It is possible to use LOVs, i.e. you can select the value of a prompt from the list of values

associated with an object. It allows a data set to be restricted to the selected values. You

can use LOVs for an object in Data Foundation or Business Layer. Different types of LOVs can be used.

LOVs based on Business Layer Objects. In this case, LOV is based on other query or on a

hierarchy that includes -

Static LOVs − It includes a list of specified values manually or imported from the file.

LOVs based on SQL − It is a value returned by a specific SQL expression.


47

Following properties can be edited for LOVs:

Column Name: This is used to edit the name of the column.

Key Column: You can select a column to be the index aware key.
