Where we need to write the code if we want to change "confirmation category" in confirmation tab using IDOC_INPUT_ORDRSP function module

Hi all,

Greetings !

I need to change the confirmation category as "AB" in the confirmations tab in ITEAM level using

IDOC_INPUT_ORDRSP function module...

I checked each and every segment in the INBOUND IDOC ..There confirmation tab details are not present in any segment..

Please let me know what to do...

I find out the EXIT "CALL CUSTOMER "008"

But I don't think so it is right one?

Please help me out..

Regards,

Swamy...
