Hi,

BW - Business Information Warehousing is a warehousing solution from SAP.

It runs on a similar 3-tier architecture as an R/3 system but it runs on OLAP (Online Analytical Processing) which is used for reporting unlike an R/3 which is based on OLTP (Online Transactional Processing).

ABAP is used in BW in the following scenarios...

->A Routine in BW is any manipulation on the data that is to be loaded into the BW system. These routines are written using ABAP.

-> User exits are used in the BW system.

-> Function Modules are mostly used.

ABAP knowledge in the following areas is used in BW.

-> Basic Data Dictionary concepts

-> String and Numeric manipulations

-> Function modules **

-> Queries (Performance optimization)

-> User exits

-> BADI

-> Subroutines

-> Debugging

and so on...

It is better to have ABAP knowledge in BW but not mandatory.

Hope that helps!
