• What is the cause and solution for SAP error message SWDP_WB_TOOL138 - View & has multiple inbound plugs - F4 help can be used for selection ?

  The SAP error message SWDP_WB_TOOL138 indicates that a view in the SAP Web Dynpro application has multiple inbound plugs, which can lead to ambiguity when trying to navigate or call the view. This situation arises when a view is designed with more than one inbound plug, and the system cannot determine which plug to use for navigation.
  Cause:
  
  Multiple Inbound Plugs: The view has been defined with more than one inbound plug, which means there are multiple entry points for navigation.
  Ambiguous Navigation: When a user or a program tries to navigate to this view, the system does not know which inbound plug to use, leading to the error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the View Definition:
  
  Open the Web Dynpro component in the SAP Web Dynpro Workbench.
  Check the inbound plugs defined for the view in question.
  
  
  
  Consolidate Inbound Plugs:
  
  If possible, consolidate the functionality of the multiple inbound plugs into a single plug. This may involve modifying the logic to handle different scenarios within a single inbound plug.
  
  
  
  Specify the Inbound Plug:
  
  If you need to keep multiple inbound plugs, ensure that the navigation to the view explicitly specifies which inbound plug to use. This can be done in the navigation logic of the calling view or component.
  
  
  
  Use F4 Help:
  
  The error message suggests that F4 help can be used for selection. This means that when navigating to the view, you can use the F4 help functionality to select the appropriate inbound plug if the system provides that option.
  
  
  
  Testing:
  
  After making changes, test the navigation to ensure that the error is resolved and that the correct inbound plug is being used.
