  • What is the cause and solution for SAP error message SWDP_WB_TOOL356 - Tray "&1" does not contain a header ?

    The SAP error message SWDP_WB_TOOL356, which states "Tray '&1' does not contain a header," typically occurs in the context of SAP Web Dynpro applications. This error indicates that the specified tray (a UI element that can hold other UI elements) is expected to have a header, but it is missing.

    Cause:

    1. Missing Header Configuration: The tray in question has been configured without a header, which is required for proper display and functionality.
    2. Incorrect UI Element Setup: The UI elements within the tray may not be set up correctly, leading to the absence of a header.
    3. Development Errors: There may be issues in the Web Dynpro component or view where the tray is defined, such as missing properties or incorrect bindings.

    Solution:

    1. Check Tray Configuration:

      • Open the Web Dynpro component in the SAP Web Dynpro Workbench.
      • Navigate to the view where the tray is defined.
      • Ensure that the tray has a header defined in its properties. You can do this by selecting the tray and checking the properties in the properties panel.
    2. Add a Header:

      • If the header is missing, you can add it by setting the appropriate property for the tray. This might involve specifying a text or a title for the header.
    3. Review UI Element Bindings:

      • Ensure that all UI elements within the tray are correctly bound to the context. Incorrect bindings can lead to display issues.
    4. Check for Development Errors:

      • Review the code in the associated controller or view for any logic that might be affecting the tray's header.
      • Look for any conditions that might prevent the header from being displayed.
    5. Test the Application:

      • After making the necessary changes, test the application to ensure that the error is resolved and that the tray displays correctly with the header.

    • SAP Documentation: Refer to the official SAP documentation for Web Dynpro for more details on configuring UI elements and handling errors.
    • SAP Community: Engage with the SAP Community forums for insights from other developers who may have encountered similar issues.
