  • What is the cause and solution for SAP error message SWDP_GENERATION023 - View element &1 inherits from multiple other view elements ?

    The SAP error message SWDP_GENERATION023 indicates that there is an issue with the inheritance of view elements in a Web Dynpro application. Specifically, it means that a view element is trying to inherit from multiple other view elements, which is not allowed in the Web Dynpro framework.

    Cause:

    The error typically arises due to one of the following reasons:

    1. Multiple Inheritance: The view element is defined in such a way that it attempts to inherit properties or attributes from more than one parent view element. In Web Dynpro, a view element can only inherit from a single parent.
    2. Model Configuration Issues: There may be a misconfiguration in the model or the way the view elements are structured.
    3. Copy-Paste Errors: Sometimes, during development, elements may be copied and pasted incorrectly, leading to unintended multiple inheritance.

    Solution:

    To resolve this error, you can follow these steps:

    1. Check Inheritance Structure:

      • Open the Web Dynpro component in the SAP Web Dynpro Workbench.
      • Navigate to the view element that is causing the error.
      • Review its properties and check the inheritance settings. Ensure that it is only inheriting from one parent view element.
    2. Modify the View Element:

      • If the view element is incorrectly set to inherit from multiple elements, modify it to inherit from only one.
      • If you need to combine properties from multiple elements, consider creating a new parent view element that consolidates the necessary properties and have your view element inherit from this new parent.
    3. Review Model Configuration:

      • Ensure that the model configuration is correct and that there are no conflicting definitions that could lead to multiple inheritance.
    4. Rebuild the Component:

      • After making the necessary changes, rebuild the Web Dynpro component to ensure that the changes take effect.
    5. Test the Application:

      • Once the changes are made, test the application to ensure that the error is resolved and that the application behaves as expected.

    Related Information:

    • Web Dynpro Documentation: Refer to the official SAP documentation on Web Dynpro for more details on view elements and inheritance rules.
    • SAP Community: Check forums and community discussions for similar issues and solutions shared by other developers.
    • SAP Notes: Look for any relevant SAP Notes that might address this specific error or provide additional guidance.

    By following these steps, you should be able to resolve the SWDP_GENERATION023 error and ensure that your Web Dynpro application functions correctly.
