• What is the cause and solution for SAP error message XMS_ADM647 - The called ABAP system '&1' is not the same as the caller system '&2'. &3 ?

  The SAP error message XMS_ADM647 indicates a mismatch between the ABAP systems involved in a communication or operation. Specifically, it suggests that the called ABAP system (denoted as &1) is different from the caller system (denoted as &2). The additional information provided in &3 may give further context about the error.
  Cause:
  This error typically occurs in scenarios involving remote function calls (RFC), where one SAP system is trying to call a function in another SAP system. The mismatch can arise due to several reasons:
  
  Different System IDs (SID): The systems involved have different system IDs, which means they are not recognized as the same system.
  Configuration Issues: There may be misconfigurations in the RFC destination settings or in the logical system settings.
  Transport Layer Issues: If the systems are part of a transport layer, there may be inconsistencies in the transport configuration.
  Network Issues: Network problems or incorrect routing can also lead to this error if the call is being redirected to an unintended system.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 and check the configuration of the RFC destination that is being used. Ensure that it points to the correct target system.
  
  
  
  Verify System IDs:
  
  Confirm that the system IDs of the caller and the called systems are correct and that you are trying to connect to the intended system.
  
  
  
  Check Logical System Configuration:
  
  Ensure that the logical system names are correctly configured in transaction SALE (for ALE/IDoc settings) or in the relevant configuration areas.
  
  
  
  Review Transport Configuration:
  
  If applicable, check the transport routes and ensure that the systems are correctly defined in the transport domain.
  
  
  
  Network Configuration:
  
  Ensure that there are no network issues preventing the systems from communicating properly. Check firewalls, routing, and any other network configurations.
  
  
  
  Consult Logs:
  
  Check the system logs (transaction SM21) and the developer traces (transaction ST11) for any additional error messages or warnings that might provide more context.
  
  
  
  Test Connection:
  
  Use the Test Connection feature in SM59 to verify that the connection to the target system is working as expected.
