  • What is the cause and solution for SAP error message WK103 - Enter a valid class ?

    SAP Error Message:
    WK103 - Enter a valid class


    Cause:

    The error message WK103 occurs when you enter an invalid or non-existent class in a workflow step or when assigning a class in SAP. This typically happens if:

    • The class you entered does not exist in the system.
    • The class is not active or has been deleted.
    • There is a typo or incorrect class name/ID.
    • The class is not assigned to the correct class type or category expected in the workflow or transaction.

    In SAP Workflow, classes are often used to define container elements or methods, so entering an invalid class disrupts the workflow configuration.


    Solution:

    To resolve the WK103 error, follow these steps:

    1. Verify the Class Name/ID:

      • Check the class name or ID you entered.
      • Make sure it exists in the system.
      • Use transaction CL02 (Change Class) or CL03 (Display Class) to verify the class.
    2. Check Class Status:

      • Ensure the class is active and not locked or deleted.
      • If inactive, activate the class.
    3. Correct Class Type:

      • Confirm that the class belongs to the correct class type expected by the workflow step.
      • For example, if a container element expects a certain class type, ensure the class matches.
    4. Use Search Help:

      • When entering the class, use the F4 help (search help) to select a valid class from the list.
    5. Check Workflow Container:

      • If the error occurs in workflow container assignment, verify that the container element is correctly defined and linked to the class.
    6. Transport and System Consistency:

      • If the class was recently created or changed, ensure it has been transported correctly to the system where the error occurs.

    Related Information:

    • Transaction Codes:

      • CL02 - Change Class
      • CL03 - Display Class
      • SWDD - Workflow Builder (to check workflow container and steps)
      • PFTC - Task Maintenance (to check task container elements)
    • SAP Notes:

      • Check SAP Notes related to workflow container and class issues if the problem persists.
    • Workflow Container:

      • Classes are often used in workflow container elements to define data types.
      • Incorrect class assignment can cause workflow errors.

    Summary:

    The WK103 error means the system expects a valid class but the entered class is invalid or not found. Verify the class exists, is active, and is correctly assigned. Use SAP class transactions and workflow tools to correct the input.


    If you provide the exact context (e.g., transaction or workflow step where the error occurs), I can give more specific guidance.
