I am having an AS2 comunication with a partner.We are exchanging EDIINT message.Till recently I was getting the message from them.All of a sudden the transactions started failing at their end with following error
An error occurred invoking the processing service wm.EDIINT.rules:processMsg for this document. The original error was com.wm.lang.flow.FlowException: sender and/or receiver unknown[/b]
[I][/i]The partner says that he has not changed anything.I have defined the external IDs for the partner in my TN profile.
I am not getting where its failing.
