How to Debug BADI_UJ_VALIDATION_RULE_LOGIC

Hello Frieds,

We Implemented the BADI ->BADI_UJ_VALIDATION_RULE_LOGIC for Validation purpose while submitting the data From BPC Front end.

I did not have front end access and I want to debug the BADI once user submit the data from front end, in order to check how the logic is working.

Can any body help me with step by step to to set debugger.

Thanks in Advance.

Sree.
