Hi
Can you please let me know how you solved your problem ? I Have the same issue. I need to issue 2 messages at time of PO creation : one for the vendor (fax or print) and one IDOC to send to Transport system (EDI). I created 2 message types etc. At PO creation, only one is issued even if in determination analysis, I see the 2 of them should be triggered but the first found in determination analysis is not there as if SAP was allowing only one message type per PO ?
Please help
