Unable to convert sender XI party

[Former Member]

Hi All,
       We recently upgraded the PI systems to version 7.3
    For a particular interface, PI system receives IDOCs from two different SAP systems. Everything works fine except this strange issue.
    I'm aware the PI generates ALEAUD01 idoc and sends back to SAP system for each idoc it receives from SAP.
    After the upgrade, I see this issue that from one SAP system PI receives IDOc but while sending back the ALEAUD01 IDOc back to that SAP system I see below error. With the another SAP system for the same interface I'm NOT seeing this error even after the upgrade. It works fine the ALEAUD01 IDoc is going back to that SAP system.

  When searched for the error log below is what I see..

But before the upgrade for the same SAP system(which is giving error now) I see log as below and it was working. There was no issue in sending back the ALEAUD01 to the SAP system.

Please have a look on the below file which guides you to deal with the IDOC Acknowledgments -

Hi Jyoti, Thanks for your reply. I'm already aware of suppressing ALEAUD01 idoc type.  In this case, as I mentioned it was working earlier. Now the question is why it is giving this error.  So without finding a answer for this I finally decided not to send ALEAUD01 idoc back to that particular SAP system.
