SAP BI Interview Questions and Answers

6) What is index? Ans: Indices/Indexes are used to locate needed records in a

database table quickly. BW uses two types of indices, B-tree

indices for regular database tables and bitmap indices for 

fact tables and aggregate tables.

7) What is KPIs (Key Performance Indicators)?

aggregated information, which is useful in making strategic

decisions.

Metric measures. KPIs are put in place and visible to an

organization to indicate the level of progress and status of change efforts in an organization.

KPIs are industry-recognized measurements on which to base critical business decisions.

8) What is t he use of process chain?

 Ans: The use of Process Chain is to automate the data load process.

Used to automate all the processes including Data load and all Administrative Tasks like indices creation deletion,

Cube compression etc.

Highly controlled data loading.

9) Difference between Display Attribute and Navigational Attribute?

 Ans: The basic d ifference between the two is that navigational a ttributes can be used to drilldown in a Bex report

whereas disp lay attributes cannot be used so. A navigational a ttribute would function more or less like a

characteristic within a cube.

To enable these features of a navigational attribute, the attribute needs to be made navigational in the cube apart

from the master data info-object.

The only difference is that navigation attributes can be used for navigation in queries, like filtering, drill-down etc.

You can also use hierarchies on navigational attributes, as it is possible for characteristics.

But an extra feature is that there is a possibility to change your history. (Please look at the relevant time scenarios) . If 

navigation attributes changes for a characteristic, it is changed for all records in the past. Disadvantage is also a

slow down in performance.

10) If there are duplicate dat a in Cubes, how would you fix it?

 Ans: Delete the request ID, Fix data in PSA or ODS and re- load again from PSA / ODS.
