• What is the cause and solution for SAP error message WRPC_XI_PROXY009 - The InternalBoundaryTypeCode &1 is not supported in this service ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRPC_XI_PROXY009: The InternalBoundaryTypeCode &1 is not supported in this service
  
  Cause:
  This error occurs when a message or proxy call contains an InternalBoundaryTypeCode value that is not recognized or supported by the target SAP service or interface. The InternalBoundaryTypeCode is typically a code used in certain business documents or interfaces (e.g., in logistics or supply chain scenarios) to specify a type of boundary or division within the document or process.
  In other words, the service or proxy you are calling expects a certain set of valid codes for the InternalBoundaryTypeCode field, but the message contains a code that is either:
  
  Not defined in the service's metadata or configuration.
  Not supported by the backend system or interface.
  Possibly a typo or incorrect value sent from the sender system.
  
  
  Typical Scenarios:
  
  Integration between SAP PI/PO and backend SAP ECC or S/4HANA systems.
  Proxy or web service calls where the message payload includes boundary type codes.
  Custom or standard IDocs or BAPIs where boundary type codes are validated.
  
  
  Solution:
  
  
  Check the value of InternalBoundaryTypeCode in the message payload:
  
  Identify the exact value passed (the placeholder &1 in the error message will be replaced by the actual code).
  Verify if this code is valid and supported by the target service.
  
  
  
  Verify the service metadata and configuration:
  
  Check the service interface (e.g., in SE80, SXMB_IFR, or ESR if using PI/PO) to see which InternalBoundaryTypeCode values are allowed.
  Confirm if the backend system supports this code.
  
  
  
  Correct the message payload:
  
  If the code is incorrect or invalid, correct it in the sending system or middleware.
  If the code is missing from the allowed list, consider extending the service or backend configuration to support it (if business-wise valid).
  
  
  
  Check for OSS Notes or SAP documentation:
  
  Sometimes SAP releases notes or patches to support additional codes.
  Search SAP Support Portal for notes related to WRPC_XI_PROXY009 or InternalBoundaryTypeCode.
  
  
  
  Debugging:
  
  If you have access, debug the proxy or service to see where the validation fails.
  Check the mapping or conversion steps in middleware if applicable.
  
  
  
  
  Related Information:
  
  InternalBoundaryTypeCode is often used in logistics documents such as delivery, shipment, or transportation units.
  The error is common in scenarios involving SAP Logistics Execution (LE), Transportation Management (TM), or Event Management (EM).
  The error message is generated by the proxy runtime or XI adapter when validating incoming messages.
  The message class WRPC relates to SAP's proxy runtime components.
