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
  
  ERROR:
  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.
