• What is the cause and solution for SAP error message STUN_ORA027 - RFC connection to system & not maintained ?

  The SAP error message "STUN_ORA027 RFC connection to system & not maintained" typically indicates that there is an issue with the Remote Function Call (RFC) connection configuration in your SAP system. This error usually arises when the system is trying to access a remote system, but the connection details for that system have not been properly maintained or configured.
  Cause:
  
  Missing RFC Destination: The RFC destination for the specified system is not created or is not maintained in the SAP system.
  Incorrect Configuration: The RFC destination may exist but is incorrectly configured (e.g., wrong connection parameters, incorrect user credentials).
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to access the target 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 code SM59 in the SAP GUI.
  Look for the RFC destination that corresponds to the system mentioned in the error message.
  If it does not exist, create a new RFC destination with the correct parameters.
  If it exists, ensure that it is correctly configured (check the connection type, target host, system number, client, user, and password).
  
  
  
  Test the Connection:
  
  In SM59, select the RFC destination and use the "Test Connection" button to verify that the connection can be established successfully.
  If the test fails, review the error message for more details and troubleshoot accordingly.
  
  
  
  Check Authorizations:
  
  Ensure that the user credentials used in the RFC destination have the necessary authorizations to access the target system.
  You may need to check the user roles and profiles in the target system.
  
  
  
  Network Configuration:
  
  Verify that there are no network issues preventing the connection (e.g., firewalls, routing issues).
  Ensure that the target system is up and running and accessible from the source system.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) and the developer trace files (transaction ST22) for any additional error messages that may provide more context about the issue.
