How to pass Selection screen values of BEx query to ECC Transaction using RRI?

Hi Experts,

We are trying to jump to ECC transaction KSB1 using RRI(Report to Report Interface) from AO report that uses a BEx query. KSB1 always defaults to the current period. Now, we want to change the posting period of KSB1 from the selected user inputs on Fiscal year and Period. We tried BADI's EXIT_SAPLRSBBS_001 & EXIT_SAPLRSBBS_002 which are of no use. Your help will be greatly appreciated on this. Thanks in advance.

Regards,

Arun
