Could you resolve this issue?
We are on PO 7.50 facing the same error message.
When we are sending any IDOCs from SAP ECC to PO, they are converted just fine and successfully transmitted to AS2 Receiver as ANSI X12.
When we receive Incoming ANSI X12 850 from AS2-Partner, it is successfully converted and transmitted to SAP ECC as IDOC. But the 997 is not sent out because of this error message. Is anything necessary for 997 other than what 855 needs?
I see them from a sending perspective as the same message, just different content.
Thanks
Marius
