SAP PO 7.50 DuplicateMessageException in SOAP XI Loop-back scenario

Dear all,

we have an integration scenario where we need to send a PI message to "ourself":

ICo #1 with SOAP XI Receiver (Adressing type “HTTP Destination”) to ICo #2 with SOAP XI Sender.

*** Update 24.04.2018 ***
In ICo #1 we want to route by OFTP virtual file name to a specific inteface for further processing in ICo #2.

ICo #1:

ICo #2:

*** End of - Update 24.04.2018 ***

But at the end of ICo #1 we get an DuplicateMessageException:

Information MP: processing local module localejbs/CallSapAdapter
Information Application attempting to send an XI message asynchronously using
connection SOAP_ 
Information Trying to put the message into the send queue 
Error Putting message into send queue failed, due to:
Message Id 55781766-3e4d-11e8-acf8-00000049615c(OUTBOUND) already exists in
duplicate check table: DB2 SQL

We understand the error that the SOAP sender tries to create a new message while taking over the message ID from the original message.

Do you have any ideas how to advise the SOAP sender to generate a new message id or any other ways to realize a loop-back scenario while preserving the message context in SAP PO?

Thank you and kind regards,

Tilo Gau

    Hi Tilo!

    Wouldn't you please clarify the point of using SOAP adapter with XI protocol in your case?

    If you are facing this error for all the soap interfaces, then restarting of Server will be helpful to resolve this issue.

      thank you for your tip. Unfortunately it restarting of the server didn't help.
