• What is the cause and solution for SAP error message TN653 - The target system is defined as a non-ABAP system ?

  The SAP error message TN653 indicates that the target system you are trying to connect to is defined as a non-ABAP system in the SAP system landscape. This typically occurs when you are attempting to perform a remote function call (RFC) or a similar operation that requires communication with another SAP system or a non-SAP system.
  Cause:
  
  System Configuration: The target system is configured in the SAP system as a non-ABAP system. This means that the system is not recognized as an SAP system that can execute ABAP programs or RFC calls.
  Incorrect RFC Destination: The RFC destination you are trying to use may not be set up correctly or may be pointing to a system that is not an ABAP system.
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the target system.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination that you are trying to use.
  Verify that the destination is correctly configured. Ensure that the target system is set up as an ABAP system if it is indeed an SAP system.
  If the target system is a non-ABAP system (like a database or a third-party application), ensure that you are using the correct type of connection (e.g., HTTP, TCP/IP).
  
  
  
  Adjust System Configuration:
  
  If the target system is an SAP system but is incorrectly defined, you may need to adjust its configuration in the SAP system landscape.
  If it is a non-ABAP system, ensure that you are using the appropriate method for communication (e.g., using web services or other integration methods).
  
  
  
  Test Connection:
  
  Use the "Connection Test" feature in SM59 to check if the connection to the target system is successful.
  If the connection fails, investigate the error messages for further clues.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis team for specific configuration settings related to the target system.
  
  
  
  Network Troubleshooting:
  
  Ensure that there are no firewall or network issues preventing communication between the SAP system and the target system.

  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to RFC connections and system configurations.
  Integration Scenarios: If you are integrating with non-SAP systems, consider using SAP PI/PO or SAP Cloud Platform Integration for better handling of such scenarios.
  
  By following these steps, you should be able to resolve the TN653 error and establish the necessary communication with the target system.
