  The SAP error message RSAR305 indicates that there is an attempt to create an RFC (Remote Function Call) destination with a name that already exists in the system. This typically occurs when you are trying to set up a new RFC destination in transaction SM59, but the name you are using is already taken by another RFC destination.
  Cause:
  
  Duplicate RFC Destination Name: The most common cause is that the RFC destination name you are trying to create already exists in the system.
  Configuration Error: There may be a misconfiguration or an oversight where the same name is being reused unintentionally.
  
  Solution:
  
  
  Check Existing RFC Destinations:
  
  Go to transaction SM59 (RFC Destinations).
  Search for the RFC destination name you are trying to create. If it exists, you can either modify it or delete it if it is no longer needed.

  Delete Unused Destination:
  
  If the existing RFC destination is not needed, you can delete it by selecting the destination and clicking on the "Delete" button.
  
  
  
  Use a Different Name:
