• What is the cause and solution for SAP error message SWDP_WB_TOOL390 - Only an inbound plug can be marked as a resume plug ?

  The SAP error message SWDP_WB_TOOL390 indicates that there is an issue with the configuration of a Web Dynpro component, specifically regarding the use of resume plugs. This error typically arises when you attempt to mark a plug as a resume plug, but it is not an inbound plug.
  Cause:
  In Web Dynpro, a resume plug is a special type of plug that allows the application to return to a previous state after a navigation event. However, only inbound plugs can be designated as resume plugs. If you try to mark an outbound plug or a plug that is not configured correctly as a resume plug, you will encounter this error.
  Solution:
  To resolve this error, follow these steps:
  
  
  Check Plug Configuration:
  
  Open the Web Dynpro component in the Web Dynpro Workbench.
  Navigate to the View or Component where the plug is defined.
  Ensure that the plug you are trying to mark as a resume plug is indeed an inbound plug.
  
  
  
  Correct Plug Type:
  
  If the plug is not an inbound plug, you will need to either:
  
  Change the plug type to an inbound plug if that fits your design.
  Remove the resume plug designation if it is not necessary for your application flow.
  
  
  
  
  
  Review Navigation Flow:
  
  Ensure that the navigation flow of your application is correctly set up. Resume plugs are typically used in scenarios where you want to return to a previous view after a user action.
  
  
  
  Test Changes:
  
  After making the necessary changes, activate the component and test the application to ensure that the error no longer occurs.
  
  
  
  Related Information:
  
  Web Dynpro Documentation: Review the official SAP documentation on Web Dynpro to understand the concepts of inbound and outbound plugs, as well as the purpose of resume plugs.
  Debugging: If the issue persists, consider using debugging tools to trace the navigation flow and identify where the configuration might be incorrect.
  SAP Community: Engage with the SAP Community forums for additional insights or similar issues faced by other developers.
  
  By following these steps, you should be able to resolve the SWDP_WB_TOOL390 error and correctly configure your Web Dynpro application.
