  • What is the cause and solution for SAP error message WA166 - Event & for object type & does not exist ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message:

    WA166 - Event & for object type & does not exist


    Meaning / Cause:

    This error occurs when you try to trigger or reference an event for a particular object type in SAP, but the specified event is not defined or does not exist for that object type.

    • Event: In SAP, events are specific triggers or actions that can be linked to business objects.
    • Object Type: This refers to the business object (e.g., BUS2032 for Purchase Order) for which the event is being called.

    The system is telling you that the event you are trying to use is not valid or not registered for the given object type.


    Common Scenarios:

    • You are trying to raise or handle an event in a workflow or business object processing, but the event name is misspelled or incorrect.
    • The event has not been created or assigned to the object type in the Business Object Builder (transaction SWO1).
    • Custom events are used but not properly defined or activated.
    • You are using a standard object but referencing an event that does not exist in the standard definition.

    How to Check / Verify:

    1. Check the Object Type and Event in SWO1:

      • Go to transaction SWO1 (Business Object Builder).
      • Enter the object type (e.g., BUS2032).
      • Check the list of events defined for this object.
      • Verify if the event you are trying to use exists.
    2. Check the Event Name:

      • Ensure the event name is spelled correctly and matches exactly (case-sensitive).
    3. Check Custom Events:

      • If you are using custom events, ensure they are created and activated properly in SWO1.
    4. Check Workflow or Program Code:

      • If the event is triggered in workflow or ABAP code, verify the event name and object type parameters.

    Solution / How to Fix:

    • If the event does not exist:

      • Create the event for the object type in SWO1 if you have the authorization and it makes sense to do so.
      • Alternatively, use an existing event that fits your requirement.
    • If the event name is incorrect:

      • Correct the event name in your workflow, program, or configuration.
    • If you are using a custom event:

      • Make sure the event is properly created and activated.
      • Transport the changes if working across systems.
    • If you are using standard objects and events:

      • Refer to SAP documentation or standard object definitions to find the correct event.

    Additional Information:

    • Transaction SWO1 is the main tool to manage business objects and their events.
    • Events are often used in SAP Workflow to trigger steps based on business object changes.
    • This error is common when integrating custom developments with standard SAP business objects.
    • Always check the SAP standard documentation or SAP Notes for the specific object type you are working with.

    Example:

    If you try to trigger event CREATED for object type BUS2032 (Purchase Order), but CREATED event is not defined for BUS2032, you will get this error.


    If you need help with a specific object type or event, please provide those details for more tailored guidance.
