  • 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:

    1. 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.
    2. 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.
    3. 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).
    4. 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.
    5. 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.

    Summary:

    Aspect Details
    Error WRPC_XI_PROXY009: InternalBoundaryTypeCode &1 not supported
    Cause Unsupported or invalid InternalBoundaryTypeCode value in the message
    Solution Verify and correct the code in the message; update service/backend config if needed
    Where to check Message payload, service metadata, backend system configuration, SAP OSS notes
    Related modules Logistics Execution, Transportation Management, SAP PI/PO proxy runtime

    If you provide the actual InternalBoundaryTypeCode value or the context (e.g., which interface or document), I can help you further with more specific guidance.
