BAdI SMOD_RSR00004 for Jump from BW Query to R/3 transaction

Hi,

I have to create a jump query to an R/3 transaction. The I/O 'Object key' in the BW corresponds to the r/3 field OBJKY of the NAST table. After trying out all the possibilities/ assignments in RSBBS(BW) also its not working.

Can anybody pls guide me how to implement BADI for this type jump query(RRI for Transaction).

Thanks in Advance,

Sandy.
