• What is the cause and solution for SAP error message CACSAPPK009 - RFC destination Sysid &1 is different from selected Sysid &2 ?

  The SAP error message CACSAPPK009 indicates a mismatch between the system ID (Sysid) of the RFC destination and the system ID of the selected system in the context of a transaction or operation. This typically occurs in scenarios involving Remote Function Calls (RFC) where the system is trying to connect to a different SAP system than intended.
  Cause:
  
  Configuration Mismatch: The RFC destination is configured to point to a different SAP system than the one you are currently working in.
  Incorrect RFC Destination: The RFC destination being used may not be set up correctly or may have been changed.
  System Landscape Changes: Changes in the system landscape, such as system copies or migrations, may lead to discrepancies in the RFC configurations.
  User Error: The user may have selected the wrong system or transaction that is not compatible with the current RFC destination.
  
  Solution:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in the SAP GUI.

  Verify that the target system ID (Sysid) in the RFC destination matches the system ID of the system you are currently logged into.
  
  
  
  Update RFC Destination:
  
  If the Sysid is incorrect, update the RFC destination to point to the correct system.
  Ensure that the connection parameters (like hostname, instance number, etc.) are also correct.
  
  
  
  Select the Correct System:
  
  If you are trying to perform an operation that requires a specific system, ensure that you are logged into the correct SAP system that matches the RFC destination.
  
  
  
  Test the Connection:
