Enhance and Populate fields using BADI

Here we will learn how to enhance fields in the Datasource  and find out which BADI needs to be enhanced .

• Get the BW data source and hierarchy tcode -->RSA6 (In this tcode we get the data sources based on the business area )

Double click the above data source and go to the extract structureàdouble click  

How append structure 

• Enhance the extract structure 

•  Append Enhance the extract structure

•  Add the required fields to the the append structure 

•  Activate the structure (better to choose enhancement category as “cannot be enhanced” )

 Now Find out where we need to code to populate the new fields

How to find the user exits/BADI ‘s  for data source  

•  Put a break point at class CL_EXITHANDLER-->Method  Get_INSTANCE -->EXIT_NAME (where you will get the BADI name ) and  Go to the tcode RSA3 and execute.

• Now you got the BADI name to SE18 and implement the same
