We are looking for the recommendations on the appropriate response for the following situation.
Receiver of 278 Request transaction (payer) does not support some of the Certification Type Code values sent in 2000E\UM02 element.
How sender of such transaction should be notified of such situation? Should it be done with 278 Response transaction where 2000E\AAA segment is sent with Reject Reason Code of '33'? Or is there a different more appropriate way?
Reject Reason Code 33 is the most appropriate rejection message for this use case.
