• What is the cause and solution for SAP error message SWDP_WB_TOOL031 - Controller use was deleted ?

  The SAP error message SWDP_WB_TOOL031 indicates that a controller that was previously used in a Web Dynpro application has been deleted. This can occur during development when changes are made to the application, such as removing or renaming controllers, which can lead to inconsistencies in the application.
  Cause:
  
  Controller Deletion: The most common cause is that a controller that was referenced in the Web Dynpro application has been deleted or renamed.

  Check Controller Existence: Verify if the controller that is causing the error still exists in the system. If it has been deleted, you will need to either restore it or remove references to it in your application.
  Update Application References: If the controller has been renamed, update the references in your Web Dynpro application to point to the new controller name.
  Rebuild the Application: After making changes, rebuild the Web Dynpro application to ensure that all references are updated and consistent.
