I have encountered a problem while integrating ECC with C4C using PI. The Sales Orders are arriving into C4C via PI but since the Party field lacks value - I believe that no ID Mapping for integration is picked up and all messages end up with application error since the Customer IDs cannot be mapped (see below):
I have checked the Payload and LocalSystemId is present in it.
Do you know what might be the reason of the Party field being empty?
I have tried to re-activate the Communication Arrangement but to no success.
Any feedback is very welcome.
