we generated a IDOC in BPM.
In ID we got for the corresponding IDOC-Message-Interface
a) Receiver determination
b) interface determination
c) receiver agreement
In SXMB_MONI we got the error "IDoc Interface XYZ could not be interpreted"
This error only occurs when the receiver is out R/3 system.
If we change the receiver e.g. to FTP, everything works find?
(IDOC is not standard SAP!)
