How To Fix WZ415 - Object type &1 inherited from &2 (no delegation)


SAP Error Message - Details

  • Message type: E = Error

  • Message class: WZ - Workflow: Model objects

  • Message number: 415

  • Message text: Object type &1 inherited from &2 (no delegation)

  • Show details Hide details
  • What causes this issue?

    The object type you specified has a parent object. There is no
    delegation between the two object types though. The events of the
    specified object type cannot therefore be triggered.

    System Response

    The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

    How to fix this error?

    You can extend the object type by adding an event. The delegation to
    the addressed parent object is not entered by the wizard though.
    Without this delegation, the new event is not triggered.
    To achieve this, you must enter the delegation between the addressed
    object types (and other superordinate object types of the parent
    object) manually.

  • What is the cause and solution for SAP error message WZ415 - Object type &1 inherited from &2 (no delegation) ?

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


    SAP Error Message:

    WZ415 Object type &1 inherited from &2 (no delegation)


    Meaning / Cause:

    This warning message occurs in the context of Workflow (WF) in SAP. It indicates that an object type (business object) &1 is inherited from another object type &2, but no delegation has been defined for the inherited object type.

    In SAP Workflow, business objects can inherit from other business objects. When inheritance is used, the system expects that the delegation of methods and events from the parent object to the child object is properly maintained. Delegation here means that the child object can use the methods and events of the parent object.

    If delegation is missing, the workflow runtime cannot properly handle the inherited methods/events, which may cause issues in workflow processing.


    When does this occur?

    • When you create or modify a business object in the Business Object Builder (transaction SWO1).
    • When you define inheritance between business objects but do not set up delegation.
    • During workflow runtime, if the system tries to access methods/events of the inherited object but finds no delegation.

    Solution:

    1. Define Delegation in Business Object Builder (SWO1):

      • Go to transaction SWO1.
      • Enter the child object type &1.
      • Navigate to the Inheritance tab.
      • Check the parent object &2.
      • Define delegation for the methods and events that should be inherited from the parent object.
      • Save and activate the business object.
    2. Check and Correct Inheritance Setup:

      • Verify that the inheritance relationship between the two objects is correctly maintained.
      • Ensure that the child object is supposed to inherit from the parent object.
      • If inheritance is not required, consider removing it.
    3. Regenerate or Re-activate Workflow Objects:

      • After fixing delegation, regenerate or re-activate the workflow objects that use these business objects.
      • This ensures that the workflow runtime recognizes the updated delegation.

    Additional Information:

    • Delegation in SAP Workflow allows a child business object to use the methods and events of its parent object transparently.
    • Without delegation, the workflow engine cannot resolve method calls or event triggers on the inherited object, leading to runtime errors or unexpected behavior.
    • This message is a warning (WZ), not an error, but it should be addressed to avoid workflow inconsistencies.
    • Proper delegation setup is crucial for workflows that rely on object inheritance to function correctly.

    Summary:

    Aspect Description
    Cause Business object &1 inherits from &2 but no delegation is defined for the inherited object.
    Effect Workflow cannot access inherited methods/events properly, causing potential runtime issues.
    Solution Define delegation for the inherited object in SWO1, then activate and regenerate workflow objects.
    Transaction SWO1 (Business Object Builder)
