• What is the cause and solution for SAP error message NAVIGATION_PROFILE201 - Multiple implementations exist for filter &! (BAdI not active!) ?

  The SAP error message NAVIGATION_PROFILE201 indicates that there are multiple implementations of a Business Add-In (BAdI) for a specific filter, and the system is unable to determine which implementation to use because the BAdI is not active. This can occur in various scenarios, particularly when customizing navigation profiles or similar configurations.
  
  Cause:
  
  Multiple Implementations: The BAdI has multiple active implementations for the same filter criteria, leading to ambiguity.
  BAdI Not Active: The specific BAdI implementation that should be used is not activated in the system.
  
  Configuration Issues: There may be issues in the configuration of the navigation profile or related settings.
  
  
  Solution:
  
  
  Check BAdI Implementations:
  
  Go to transaction SE18 (BAdI Definition) and enter the name of the BAdI that is causing the issue.
  Check the list of implementations for that BAdI using transaction SE19 (BAdI Implementation).
  Identify if there are multiple active implementations for the same filter.
  
  
  
  Activate the Correct Implementation:
  
  If you find that the required implementation is not active,
