OPERATIONAL DATA PROVISIONING (ODP)
Operational Data Provisioning provides a technical infrastructure that supports
• Data extraction and replication scenarios between various sources (ODP Providers) and target application (ODP Consumers).
• It supports delta mechanisms and queueing of data in the so called Operational Delta Queue (ODQ).
• The ODP Framework is installed on the respective source system independently from SAP BW or SAP BW/4HANA (eg. in PI_BASIS)
• With the ODP Source System in SAP BW or SAP BW/4HANA data can get directly processed from the ODQ to data targets (Advanced DataStore Objects / InfoObjects) without using the Persistent Staging Area (obsolete in SAP BW/4HANA)

BW/4HANA: NATIVE SQL ACCESS
SAP BW/4HANA logic and data can be exposed to SAP HANA. Automatic generation of SAP HANA views allows:
• SQL logic on top of generated views
• Combined data from native SAP HANA
• SQL access for front-end tools
Generated SAP HANA views are part of
• SAP BW/4HANA lifecycle
• SAP BW/4HANA security
Based on local HANA schema tables
INTEGRATING EXTERNAL SYSTEMS AND DATABASES TO SAP BW/4HANA
Technical Integration Scenarios
SAP BW/4HANA – BIG DATA INTEGRATION

Enhance data with Advanced Analytics using HANA specific libraries (AFL), R-Script or a custom HANA procedure
Predictive Text AnalysisData MiningMachine Learning
In-Memory Data Warehousing
Query all data at the speed of SAP HANA
No Aggregates or Roll-up ProcessesNo Performance Specific ObjectsFewer IndexesFaster Loading and Processing
Algorithm Push-down
Significant performance gain through push-down of operations/calculations
OLAP Engine, complex query calculations (e.g. exception aggregation)Planning functionsData management (e.g. transformation logic)
• Easy Integration of Big Data Scenarios
• IT Cost Reduction, Development Productivity
• Development Productivity, Faster Time to Value for the Business
• New Capabilities, Reduction of TCO
BUSINESS VALUE DRIVERS FOR BW/4HANA
• Preparing your system
• Options for migration
STRATEGY TO MOVE TO BW/4HANA
• Check Your BW System Before /After Migrating to SAP HANA• Size via Automated Sizing Tool• Lower TCO by Leveraging Non-active Data Concept and Off-loading Data to
Near-line Storage• Perform Housekeeping Task Regularly• Leverage Automated Task Lists• Validate SAP HANA Configuration, Check Table Consistency and Monitor
Delta Merge• Convert Data Flows and InfoProviders• Check Best Practices for ABAP on HANA• Check SAP Note 1909597
HOW TO PREPARE YOUR CURRENT SYSTEM
• Add-On “SAP BW/4HANA Starter” (f.k.a. “SAP BW, Edition for SAP HANA”) is prerequisite for In-Place Conversions
IN-PLACE CONVERSION TO SAP BW/4HANA SAP BW/4HANA STARTER ADD-ON
▪ Unsupported object types cannot be created
▪ Existing scenarios can continue running as before
▪ Unsupported objects canbe changed when adding them to a white list
▪ No imports of unsupported object types
▪ White list is not relevant any more
▪ System is ready for component conversion

SAP BW
• Also referred to as “greenfield approach”, this path start by installing a brand new SAP BW/4HANA system. There is a new automated task list available to simplify the basic system setup tasks, like creating and configuring the SAP BW/4HANA background user, setting the SAP BW/4HANA client and installing the essential technical content.
• There are two basic options for configuring your new SAP BW/4HANA system. • Either it can begin from scratch, connect any data sources – that could be a legacy
data warehouse• Or any other data source available in your enterprise – and start modeling the
data warehouse. It is highly recommend following our layer scalable architecture framework (LSA++).
• To start from an existing SAP Business Warehouse (BW) system, certain configuration and data models can be transported from your existing landscape to SAP BW/4HANA.
GREENFIELD IMPLEMENTATION
CONSOLIDATE AND SIMPLIFY
• This is to optimize more complex data warehousing landscapes resulting in a single, global SAP BW/4HANA system.
• One reason could be that there are multiple legacy or SAP BW systems which is required to consolidate on the mighty SAP HANA platform.
• Another could be to carve out selected data models or flows into an existing SAP BW/4HANA system.
• One of the innovative tools is the “System Comparison Workbench” which can show the differences between several regional SAP BW systems and help define a strategy to integrate these into a global data model.
LANDSCAPE SIMPLIFICATION
• A clear governance and guidance needs to be defined
• EDW Layer should be either in BW or HANA
• Usage of BWonHana Objects and SQL-Programming needs some experience
• Data streaming requires new skills and has some complexity
• Performance is not always a "Quick Win"
LESSONS LEARNT
• BW/4HANA is an open DWH and combines the functionality of a relational DWH and a BW
• Reduction of BW objects leads to faster implementation
• SQL based transformations are stabile and fast
• Data Streaming and Flow Graphs offer new use cases
• With BWonHANA we can reload our entire data into the DWH within 1 weekend
