Workflow Ends in Error " No auth to send IDocs with message type ORDRSP"

Hello All,

I have created an RFC user with limited Authoprizations including WE* tciodes and a few ME* transactons for an ALE Set up. I want to make sure i would not be giving more authorizations (extensive) to this RFC user and assign Just required authorizations. So i started testing testing and the inbound IDOC ended in error with a message " No auth to send IDocs with message type ORDRSP" Message no. SR053. Is there any way to find out what is the missing authorization object for the User. Any inputs would be really apprecaited.

Br,

Sri
