Answer You have a function called 'extract' in cognos.

Ex:- extract(month,the dte field). by giving like this you will get month. so you can keep a filter to restrict the rows only for october.

Questions shud be more clearer. Cognos meaning , impromptu or powerplay or reportnet of cognos 8.0 ? If it is impromptu then just add a text column and connect it to data field say for eg. 'Report from to

Answer Problem Description

What are looping joins and how do you resolve them?

Solution Description

Looping joins could potentially return incorrect data.An example of a looping join,

B -> CA -> < > -> DE -> F

When you select an item from table A and D, Impromptu will try to choose the shortest path, e.g. if A -> D existed, then this is the path Impromptu will take. But in the above situation, the two paths are equal and so Impromptu has to make a choice, e.g. "A -> B -> C -> D" OR "A -> E -> F -> D". Impromptu makes it's choice based on how the catalog was constructed, which cannot be altered once it's created; order of the tables in the catalog.The two paths could return different results depending on the relationship between the tables in the path.The report would be fine IF Impromptu chose the expected path. The choice is not always right.

Eliminating looping joins prevents Impromptu from making the wrong choice. To eliminate looping joins, you can either break unnecessary joins, e.g. reports do not need a join between table F and D, e.g.

B -> C -> DA -> < E -> F

But if you need all the joins, use ALIAS tables to break the looping join. Add an alias table for table A and break the join from table A and E, e.g.

A -> B -> C> -> DAlias A -> E -> F

Both solutions could affect existing reports.

Created:Nov 04, 1999

Applies To:Impromptu - 2.0Impromptu - 3.01Impromptu - 3.03Impromptu - 3.04Impromptu - 3.5Impromptu - 4.0Impromptu - 5.0Impromptu - 7.1

--------------------------------------------------------------------------------

Problem Description

Under the Joins dialog on the Analyze Tab it states a Loop join is present. What does this mean and how can it be resolved?

Solution Description

A Loop Join occurs when there are multiple paths between database tables. An example of this is A joins to B and B joins to C and C joins to A.

The proper definition of join strategies in an Impromptu catalog is crucial to the success of an ad-hoc reporting environment. Impromptu shelters the user from having to know any of the technical information about the database, including name, location, table and column names, and join strategies. The Impromptu Administrator must be very thorough in their definition and testing of the join strategies. Impromptu provides an ability to analyze the joins and determine any anomalies. The most common is the Loop Join.

The implications of the loop join is that there is no way to predetermine which of the various join paths will be used by Impromptu when creating the SQL. SQL is dynamically generated for each report as it is created and before it executes. For example, to create a report using columns from tables A and C, we could join from A=>B=>C or directly from A=>C. In some cases, both of these joins would

result in the same data being retrieved. However, in other cases it may result in different data. Impromptu will always try to use the shortest route in joining multiple tables. It will also try to use the tables that are already included in the query, rather than including an additional table.

There is no hard and fast rule to resolving Loop Joins. There are four basic resolutions:1. Break the join2. Create alias tables with different join strategies3. Use the join expression editor to specify the join4. Modify SQLEach of these resolutions is done for a different reason and may have some issues associated with it. Determine the best resolution for your situation by analyzing the data with regards to the results required from the join structure.

Example:

The join structure looks like this:

A = BA = CB = C

This is producing incorrect results. To resolve this issue, make table C an alias to omit the loop in the join structure and this will result in data displaying correctly.

Correct Join Structure:

A = BA = C aliasB = C

What type problems we can face in general at report runnig time

Answer The most common problems are -

1.No Data Appears in the Report (to remove this check data source or package)

2.Unexpected or incorrect values appears in reports , may be report is running with limited data

3.The report filter does not work, values are not coming in filter option

4.report is not able to oprm in excel ,cvs or xml

Explain how to create powerplay reports

Answer To create a powerplay report

1)You have to create a IQD file from impromptu by saving IMR report as IQD

2)Use Frame Work manager model and externalise the query subject you want to use in powerplay transformer and powerplay

When you have the IQD file published to a location such as UNC

Go to powerplay transformer model and select new ,

select the data source name , and IQD file location either published from FM or Impromptu (saved as IQD)

You will see all the query items in the explorer then you can specify the dimensions like time and measures.

Then generate categories for the dimensions and measures .

Right click the cube and select create power cube , after that view the cube in cognos powerplay explorer.

We can also publish the cube to PPES(Powerplay enterprise server)

Publish the cube to the upfront

Use powerplay web explorer to view the cube

What are versions of cognos from starting release to latest in the market

Answer I dont know the starting release but can be version 5, latest version is 8.3 then reportNet 1.1.

What are different datasources to develop models

Answer Work with Source Data

Transformer supports a wide range of local data sources, including

? Impromptu query definition files (.iqd), which can query local or server-based databases

? delimited ASCII

files (.asc) and comma-separated variable files (.csv)

? fixed-field text files

? local databases, including Microsoft Access, which can specify SQL queries against local or

server-based databases, Clipper, dBase, FoxPro, and Paradox

? PowerHouse portable subfiles

? spreadsheet crosstabs and databases, including Excel

and Lotus 1-2-3What is Cognos Visualizer and Cognos Scripting?

Answer Visualizer is a representation of data cubes in a dashboard format. We can drill through to the ground level of a hierarchy as like in power play report but cannot add or remove fields dynamically.

Cognos script editor : We can write cognos macros or programs in this tool and can fine tune or process some execution

What is loop in frameworkmanager ?

Answer Loop: loop is a closed path (relation) that exists among 3 (or) more tables. For example

, if we have '3' tables T1, T2, T3 then, a loop exists among these tables only when we create joins in the following fashion:

Loop: T1 ---> T2 ---> T3 ---> T1

To resolve the above problem, we have to create a shortcut (or) Alias to the Table T1.

No Loop: T1 ---> T2 ---> T3 ---> Alias (or) Shortcut of T1How u can connect different database in reportnet?wht is the extension file to save a template?give example for drillthrough and masterdetail reports in CRM domain?

Answer Template?extension is .imt1.What are differences between Reporter report and Explorer report?

Answer An Explorer report is used to explore the contents of the cube.,The multidimensional structure.A Reporter report is used to add/modify the contents of the cube.

What is the difference b/w macros and prompt?

Answer Macro-A macro is a set of instructions that can run applications.Example : A macro can open your catalog,select a report(say for instance) convert that to another format and export it to any specified location,provided the code (Program)is such.Prompt-A prompt specifies the manner in which data in the reports are to be displayed.A Prompt can be defined at the catalog level either or during report generation.

Give me any example of semi and non additive measures?Semi-Additive: Semi-additive facts are facts that can be summed up for some of the dimensions in the fact table but not the others. Non-Additive: Non-additive facts are facts that cannot be summed up for any of the dimensions present in the fact table. Current Balance and Profit

Margin are the facts.Current Balance is a semi-additive fact as it makes sense to add them up for all accounts (what's the total current balance for all accounts in the bank?) but it does not make sense to add them up through time (adding up all current balances for a given account for each day of the month does not give us any useful information). Profit Margin is a non-additive fact for it does not make sense to add them up for the account level or the day level.

How can I create a dynamic column name in Cognos1. add a data item to the query(the query on which the report is based)2. define an expression which u want to use for the dynamic column label3. from the report page click on the column label4. from properties pane look for "column label" the default would be "data item label/name" change that to "data item value"5. in the same pane change the "data item" property to have the data item that u created for the column label.

What is meant by Junk Dimension?

A "junk" dimension is a collection of random transactional codes flags and/or text attributes that are unrelated to any particular dimension. The junk dimension is simply a structure that provides a convenient place to store the junk attributes. A good example would be a trade fact in a company that brokers equity trades. The fact would contain several metrics (principal amount net amount price per share commission margin amount etc.) and would be related to several dimensions such as account date rep office exchange etc. This fact would also contain several codes and flags that were related to the transaction rather than any of the dimensions ... such as origin code (that indicates whether the trade was initiated with a phone call or via the Web) a reinvest flag (that indicates whether or not this trade as was the result of the reinvestment of a dividend payout) and a comment field for storing special instructions from the customer. These three attributes would normally be removed from the fact table and stored in a junk dimension ... perhaps called the trade dimension. In this way the number of indexes on the fact table would be reduced and performance (not to mention ease of use) would be

enhanced. Hope this helps.

what is the difference between a cascading report and drillthru report?why do we go for drill thru report?

Drill Through is used to link the master & detail reports.After putting drill through if you click on a link (e.g. Order ID 1234) in the master report then the details will be displayed for that particular item (Order ID 1234).

Cascading prompt uses the value from the previous prompt to filter the value in the current prompt.

  For Cascading no need of two reports.If a report having two related columns (e.g. Country & States),then we can cascade these two columns by adding two value prompts.

If you select a country (e.g INDIA),in the next prompt all the states will be displayed those which are under INDIA.

If you want to see the details for the state Tamilnadu,then select TN from the list which will display all the details for TN.
