• What is the cause and solution for SAP error message SWDP_WB_TOOL322 - You cannot create a navigation link between two inbound plugs ?

  The SAP error message SWDP_WB_TOOL322 indicates that you are trying to create a navigation link between two inbound plugs in a Web Dynpro application, which is not allowed. In Web Dynpro, inbound plugs are used to receive navigation requests from other components, and they are not designed to be linked directly to each other.
  Cause:
  The error occurs when:
  
  You attempt to create a navigation link between two inbound plugs of different views or components.
  The navigation link is incorrectly configured in the Web Dynpro component's configuration.
  
  Solution:
  To resolve this error, you should:
  
  
  Check the Navigation Links: Ensure that you are creating navigation links between outbound plugs (which can initiate navigation) and inbound plugs (which can receive navigation). You cannot link two inbound plugs directly.
  
  
  Correct Configuration:
  
  Identify the outbound plug from which you want to navigate.
  Ensure that the target view has an appropriate inbound plug defined to receive the navigation.
  Create the navigation link from the outbound plug of the source view to the inbound plug of the target view.
  
  
  
  Review Component Structure: Make sure that the component structure is correctly set up, and that the views and their respective plugs are properly defined.
  
  
  Use the Web Dynpro Component Configuration: Open the Web Dynpro component in the Web Dynpro Workbench (transaction code SE80 or WDWB) and check the configuration of the views and their plugs.
  
  
  Related Information:
  
  Web Dynpro Concepts: Familiarize yourself with the concepts of inbound and outbound plugs in Web Dynpro. Inbound plugs are used to receive navigation requests, while outbound plugs are used to initiate navigation.
  Documentation: Refer to the official SAP documentation on Web Dynpro for more detailed information on navigation and plug configurations.
  Debugging: If the issue persists, consider using debugging tools to trace the navigation flow and identify where the configuration might be incorrect.
  
  By following these steps, you should be able to resolve the error and successfully create the desired navigation links in your Web Dynpro application.
