  The SAP error message /UI2/FDM302 Target Mapping &1&2: Exists already in Catalog &3 as original typically occurs in the context of SAP Fiori and the configuration of target mappings in the Fiori Launchpad. This error indicates that there is an attempt to create a target mapping that already exists in the specified catalog.
  Cause:
  
  Duplicate Target Mapping: The error is triggered when you try to create a target mapping (for example, a tile or a link) that already exists in the specified catalog. This can happen if:
  
  You are trying to add a target mapping with the same ID or properties as an existing one.
  There was a previous configuration that was not properly deleted or modified.
  
  
  
  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/FLP or /UI2/FLP_CATALOG) and check the target mappings in the specified catalog.
  Look for the target mapping with the same ID and properties.
  
  
  
  Modify or Delete Existing Mapping:
  
  If you find the existing target mapping that conflicts with your new entry, you can either:
  
  Modify the existing target mapping to meet your requirements.
  Delete the existing target mapping if it is no longer needed.
  
  
  
  
  
  Create a Unique Target Mapping:
  
  If you need to keep the existing mapping, consider creating a new target mapping with a different ID or properties that do not conflict with the existing ones.
  
  
  
  Transport Requests:
  
  If you are working in a development environment and plan to transport changes to a production environment, ensure that the target mappings are correctly included in your transport requests.
