• What is the cause and solution for SAP error message FDM_MIRROR008 - Logical name &1 for an original system has already been registered ?

  The SAP error message FDM_MIRROR008 indicates that there is an issue with the logical name of a system that has already been registered in the context of the Financial Data Management (FDM) module. This error typically arises when you attempt to register a logical system name that is already in use or has been previously registered in the system.
  Cause:
  
  Duplicate Registration: The logical name you are trying to register is already associated with another system or has been registered previously.
  Configuration Issues: There may be inconsistencies in the configuration settings or the system landscape that lead to this error.
  Transport Issues: If you are transporting configuration settings between systems, the logical name might have been included in the transport and already exists in the target system.
  
  Solution:
  
  
  Check Existing Registrations: 
  
  Go to the relevant transaction (e.g., SPRO for configuration) and check the list of registered logical systems. Ensure that the logical name you are trying to register is not already in use.
  You can also use transaction BD54 to view and manage logical system names.
  
  
  
  Use a Different Logical Name: 
  
  If the logical name is indeed already registered and you need to register a new system, consider using a different logical name that is not currently in use.
  
  
  
  Delete or Modify Existing Registration: 
  
  If the existing registration is no longer needed, you can delete it or modify it as necessary. Be cautious with this approach, as it may affect other configurations or systems.
  
  
  
  Check Transport Requests: 
  
  If the error occurred after a transport, check the transport requests to ensure that they did not inadvertently include the logical name that is causing the conflict.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to FDM and logical system registration for any specific guidelines or updates that may apply to your version of SAP.
