• What is the cause and solution for SAP error message CLMM854 - Target system is unknown or the same as the source system ?

  The SAP error message CLMM854 indicates that there is an issue with the target system configuration in the context of a system copy or transport operation. Specifically, it suggests that the target system is either not recognized (unknown) or is the same as the source system, which is not allowed in certain operations.
  Cause:
  
  
  Unknown Target System: The target system may not be properly defined in the SAP landscape or the system configuration. This could happen if the target system has not been registered or if there are connectivity issues.
  
  
  Same Source and Target System: The operation you are trying to perform (like a system copy or transport) requires a distinct target system. If the source and target systems are the same, the operation cannot proceed.
  
  
  Solution:
  
  
  Check Target System Configuration:
  
  Ensure that the target system is correctly defined in the SAP system landscape. You can do this by checking the system settings in transaction SCC4 or SMLT.
  Verify that the target system is reachable and that there are no network issues preventing communication.
  
  
  
  Use a Different Target System:
  
  If you are trying to perform an operation that requires a different target system, ensure that you specify a valid and distinct target system that is not the same as the source system.
  
  
  
  Review Transport Routes:
  
  If you are working with transport requests, check the transport routes in transaction STMS to ensure that the target system is included in the transport landscape.
  
  
  
  System Alias:
  
  If you are using system aliases, ensure that the alias is correctly configured and points to the intended target system.
  
  
  
  Authorization:
  
  Ensure that you have the necessary authorizations to perform operations on both the source and target systems.
