Data Validation of webi report built on top of SAP BW

Hi Folks,

             After generating my Webi Report I want do data validation test as part of my UNIT testing

             1) If the report built on top of any RDBMS Databases like SQL or Oracle we can go back to tools like TODE and we can run our report sql against Database to cross-check the data

             2) Here my question is what if the report built on top SAP BW in which way we can do data validation testing?

Many Thanks

Kind Regards

Raki
