  SAP Error Message:
  WEBDYNPRO_RT029: Use only main window views for the registration
  
  Cause:
  This error occurs in SAP Web Dynpro applications when you try to register a view that is not a main window view. In Web Dynpro, only views that belong to the main window can be registered for certain operations like navigation or event handling. If you attempt to register a view that belongs to a different window (e.g., a popup window or a secondary window), the system raises this error.
  
  Explanation:
  
  Main Window Views: These are views that are part of the main window of the Web Dynpro component.
  Non-Main Window Views: Views that belong to other windows such as popup windows or dialog windows.
  The registration process (e.g., for navigation or event handling) expects views from the main window only.
  Registering views from other windows is not supported and leads to this error.
  
  
  Solution:
  
  
  Check the View Registration:
  
  Verify which view you are trying to register.
  Ensure that the view belongs to the main window of the Web Dynpro component.
  
  
  
  Adjust the View:
  
  If the view is part of a popup or secondary window, consider moving the view to the main window if registration is necessary.
  Alternatively, change your design so that only main window views are registered.
  
  
  
  Review Navigation and Event Handling Logic:
  
  Make sure that navigation or event registration logic targets only main window views.
  If you need to interact with views in other windows, use appropriate methods that do not require registration.
  
  
  
  Check Web Dynpro Component Configuration:
  
  In the Web Dynpro component, verify the window and view assignments.
  Confirm that the views you want to register are assigned to the main window.
  
  
  
  
  Additional Information:
  
  This error is common during development or customization of Web Dynpro applications.
  It helps maintain the integrity of the navigation and event handling framework by restricting registration to main window views.
  If you are unsure which views belong to the main window, check the Web Dynpro component's window and view hierarchy in the Web Dynpro Explorer or the Component Controller.
