2587575 - Load Balancing SOAP Adapter Acknowledgements in backend system


  • You are using SAP Process Integration (PI) or Process Orchestration (PO) with a SOAP Adapter scenario
  • In this case, the scenario is ECC -> SOAP Sender with XI 3.0 mode (i.e. ABAP proxy) -> PI -> SOAP Receiver -> Third party Web Service
  • In the NetWeaver Administrator you have configured a HTTP Destination to handle the routing of Acknowledgements back to ECC
  • This destination is then configured in the SOAP Sender channel
  • You wish to load balance the acknowledgements on ECC by using the Message Server host and port
  • The acknowledgement messages fail in PI and do not reach the ECC system
  • The error below is visible in the PI Audit Log

    Transmitting the message to endpoint <local> using connection AFW failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: unable to get URLConnection: java.io.IOException: HTTP Response code 500 received.
