• What is the cause and solution for SAP error message WD379 - Outcome "&" is already defined for step "&". Property ("&"<>"&"). ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  SAP Error Message:
  WD379 Outcome "&" is already defined for step "&". Property ("&"<>"&").
  
  Cause:
  This error occurs in Web Dynpro ABAP applications during the configuration of navigation outcomes in a Web Dynpro component controller or view controller.
  
  The message indicates that you are trying to define an outcome (navigation target) with a name that has already been defined for the same step (view or component controller).
  In Web Dynpro, each step (view or component controller) can have multiple navigation outcomes, but each outcome name must be unique within that step.
  The error typically arises when:
  
  You accidentally define two navigation outcomes with the same name in the same step.
  You copy-paste navigation outcomes without changing their names.
  There is a mismatch or duplication in the navigation properties or outcome names in the Web Dynpro component.
  
  
  
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Check Navigation Outcomes:
  
  Open the Web Dynpro component in the Web Dynpro Explorer.
  Navigate to the Navigation tab of the relevant view or component controller.
  Review the list of defined outcomes for the step mentioned in the error message.
  
  
  
  Ensure Unique Outcome Names:
  
  Make sure that each outcome name is unique within the step.
  Rename or remove duplicate outcomes as necessary.
  
  
  
  Check Property Bindings:
  
  The error message also references properties (Property ("&"<>"&")), which means the navigation outcome might be linked to a property.
  Verify that the property names used in the navigation outcomes are correctly defined and unique.
  
  
  
  Clean and Rebuild:
  
  After correcting the navigation outcomes, save and activate the component.
  Sometimes, cleaning the project or restarting the SAP GUI/Web Dynpro environment helps clear cached metadata.
  
  
  
  Test Navigation:
  
  Run the Web Dynpro application and test the navigation to ensure the error no longer occurs.
  
  
  
  
  Related Information:
  
  
  Web Dynpro Navigation:
  
  Navigation outcomes are used to define possible navigation paths from one view or component controller to another.
  Each outcome is identified by a unique name and can be triggered programmatically or via UI elements (buttons, links).
  
  
  
  SAP Notes and Documentation:
  
  Check SAP Help Portal for Web Dynpro ABAP navigation concepts.
  Search for SAP Notes related to WD379 if the problem persists after correcting duplicates.
  
  
  
  Common Mistakes:
  
  Copying views or components without adjusting navigation outcomes.
  Defining outcomes with generic names like "OK", "Cancel" multiple times in the same step.
  
  
  
  
  Summary:
  
  
  
  Aspect
  Description
  
  
  
  
  Cause
  Duplicate navigation outcome name defined for the same step in a Web Dynpro component.
  
  
  Solution
  Ensure all navigation outcome names are unique within the step; correct or remove duplicates.
