Problem in getting the response from BAPI--Urgent

Hi All,

My scenario is File to RFC. I've used a BPM here. I collected all my records and made a asynchorouns BAPI call. I ve used correlation to get the correct response.

My BPM looks to be as follows:-

Recieve step -> Transformation >Block(For each) >BAPI call(async call) ->recieve step(to collect response) ->End Block -->

Now my problem is how to configure my recieve step to collect my BAPI response since i'm calling my BAPI asynchorously. Am I need to create one more sender agreement by configuring the sender RFC adapter...If so how my BAPI response will be triggered from the BAPI. Please guide me asap.

Waiting for ur reply.

Regards,

Dhana
