  Test the RFC Connection:
  
  After creating or updating the RFC destination, use the "Test Connection" feature in SM59 to verify that the connection works.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the function has the necessary authorizations to access the RFC destination.
  
  
  
  Review Network Settings:
  
  Check for any network issues that might be preventing the connection to the target system. This includes firewall settings, VPN connections, etc.
  
  
  
  Check System Name:
  
  Ensure that the system name used in the call matches the name defined in the RFC destination.
