  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Target Mappings:
  
  Go to the Fiori Launchpad Designer or the relevant transaction (like /UI2/FLPCM_CUST) to view the existing target mappings.
  Look for the target mapping with the same ID as indicated in the error message.
  
  
  
  Modify or Delete Existing Mapping:
  
  If you find a duplicate target mapping that you do not need, you can delete it or modify it as necessary.
  If the existing mapping is required, consider changing the ID of the new target mapping you are trying to create.
  
  
  
  Review Catalogs:
  
  Ensure that you are working with the correct catalog and that there are no unintended duplicates across different catalogs.
  
  
  
  Transport Requests:
  
  If you are working in a development environment and planning to transport changes, ensure that the target mappings are correctly included in the transport request.
