    Error Message

    WXCM004: No function module has been saved for the combination & &


    Cause

    This error occurs in SAP when the system tries to call a function module based on a certain combination of parameters (usually related to a business object, event, or context), but no function module has been assigned or saved for that specific combination.

    In other words, the system expects a function module to be linked to a particular combination of values (e.g., object type and event), but it cannot find any function module assigned to handle that combination.

    This typically happens in scenarios involving:

    • Business Object Event Handling (e.g., in Workflow or Business Object Repository (BOR))
    • Change Pointers or Change Documents
    • Custom Enhancements or User Exits where function modules are dynamically called based on configuration

    Common Scenarios

    • In BOR (Business Object Repository), when an event is triggered, the system looks up the function module assigned to that event for the object. If none is assigned, WXCM004 is raised.
    • In Workflow, when an event triggers a function module call, but the link is missing.
    • In Change Pointer processing, if the function module for a particular object and change pointer combination is not maintained.

    Solution

    1. Check the Configuration:

      • Identify the combination of parameters (e.g., object type and event) for which the function module is missing.
      • Go to the relevant customizing or configuration transaction where function modules are assigned to these combinations.
    2. Assign or Create the Function Module:

      • If a function module exists but is not assigned, assign it to the combination.
      • If no function module exists, create one that handles the required processing and assign it.
    3. For BOR Objects:

      • Use transaction SWO1 to check the business object.
      • Navigate to the event in question.
      • Check the function module assigned to the event.
      • If missing, assign the correct function module or create one.
    4. For Change Pointers:

      • Use transaction BD50 or BD52 to maintain function modules for change pointers.
      • Ensure the function module is assigned for the object and change pointer combination.
    5. For Workflow:

      • Check the event linkage in the workflow builder or event linkage customizing.
      • Assign the function module or event handler accordingly.
    6. Debugging:

      • If unsure about the combination causing the error, debug the program or workflow to find the exact parameters passed.
      • Use the error message variables (& &) to identify the missing combination.

    Related Information

    • Transaction SWO1: Business Object Builder
    • Transaction BD50 / BD52: Change Pointer Function Module Assignment
    • Transaction SWE2: Event Linkage
    • SAP Note / Documentation: Search for WXCM004 in SAP OSS Notes for any specific patches or known issues.
    • Function Module Naming: Usually, function modules for BOR events follow a naming convention like BOR_EVENT_<Object>_<Event>.
    • SAP Help Portal: Look for documentation on BOR, Workflow, and Change Pointers.

    Summary

    Aspect Details
    Cause No function module assigned for a specific combination of parameters (e.g., object/event)
    Effect System cannot process the event or action, resulting in error WXCM004
    Solution Assign or create the required function module for the combination in the relevant config
    Key Transactions SWO1, BD50, BD52, SWE2

    If you provide the exact parameters (the values of the placeholders & &), I can help you identify the exact combination and guide you more specifically.
