The Sender shows me all properties correctly set in Reports. The same document is configured on receiver side which is also a B2B. The receiver does show the file but throws Document protocol identification error. The receiver fails to identify Sender, document protocol version etc. The Sender receives back Ack for unexpected processing error.
If it works correctly I want to make it a bit general by reading FROM_PARTY and TO_PARTY from my Xml file in Mediator.
