    1. Assign a Layout Manager:

      • Open the Web Dynpro component in the SAP Web Dynpro Workbench.
      • Navigate to the container that is causing the error.
      • Ensure that a layout manager (e.g., VerticalLayout, HorizontalLayout, GridLayout, etc.) is assigned to the container.
      • If it is missing, add an appropriate layout manager to the container.
    2. Check Component Configuration:

      • Review the component configuration to ensure that all necessary elements, including layout managers, are properly defined.

      • After making changes, rebuild the Web Dynpro application to ensure that all changes are applied correctly.
      • Test the application to verify that the error has been resolved.
    4. Review Documentation:

      • Consult the SAP documentation for Web Dynpro to understand the requirements for layout managers and containers.
      • Look for examples or best practices regarding the use of layout managers in Web Dynpro applications.

    Related Information:

    • Web Dynpro Layout Managers: Familiarize yourself with the different types of layout managers available in Web Dynpro and their use cases.
