Incorrect message type in IDOC for Purchase order change

Question

Hi Gurus.
Please advise on below.
We have several purchase orders that are configured to trigger IDOC upon change. But accidentally, someone has deactiveted the automatic proposal of EDI message type for these Purchase orders which resulted to not transmitting purchase order change documents automatically.
As a workaround, we have proposed to create EDI message manually during Purchase order change. But upon checking in tcode WE09, message type is ORDERS which is PO create instead if ORDCHG for purchase order change.
Please kindly advice on why it is behaving like this for purchase orders with EDI message previously deactivated.
Thanks in advance.

To simulate.
Create PO. go to messages, select EDI message then deactivate permanently. Save PO. Release PO if needed. Change PO. go to messages, EDI is not automatically proposed. create EDI message mamanually. Save PO. Release PO id needed. check tcode WE09, for PO create, no IDOC since it was deactivated permanently. For PO change, IDOC was triggered but with incorrect message type ORDERS instead of ORDCHG.

Hi Acel,
You will need to check the settings in transaction WE20 - You will be using a Partner Profile to determine the outbound message, either for each vendor or a generic one.
on the outbound parameters, you will need to ensure that ORDCHG is set up as a message type. If not, add it, ensuring that you use the message ORDCHG, the basic type (or extension) that you are using, usually ORDERS05 and make sure that in message control, you have process code ME02 set up. This should enable the correct message type to be determined.
