• What is the cause and solution for SAP error message ESH_ADM_MSG212 - The old and new system ID '&1' as well as the client '&2' are identical ?

  The SAP error message ESH_ADM_MSG212 indicates that there is an issue with the system ID (SID) and client configuration during a system copy or migration process. Specifically, the error states that the old and new system ID, as well as the client, are identical, which is not allowed in certain operations.
  Cause:
  This error typically occurs in scenarios such as:
  
  When you are trying to perform a system copy or a system refresh, and the system ID (SID) or client number you are trying to assign to the new system is the same as that of the existing system.
  The operation you are attempting requires a unique SID or client number to differentiate between the old and new systems.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check System ID and Client Configuration:
  
  Ensure that the new system you are trying to create has a different system ID (SID) and client number than the existing system. You can do this by reviewing the configuration settings in the SAP system.
  
  
  
  Modify the SID/Client:
  
  If you are performing a system copy, ensure that you specify a new SID and client number that do not match the existing system. This may involve changing the parameters in the system copy process.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation for the specific procedure you are following (e.g., system copy, system refresh) to ensure you are adhering to the requirements for SID and client configuration.
  
  
  
  Use SAP Tools:
  
  If you are using tools like Software Provisioning Manager (SWPM) or other SAP tools for system copy, ensure that you follow the prompts correctly and provide unique identifiers as required.
  
  
  
  Check for Existing Clients:
  
  If you are trying to create a new client in an existing system, ensure that the client number you are trying to create does not already exist in the system.
