  Causes:
  
  Network Issues: Problems with the network connection between the SAP system and the target system can lead to communication errors.
  Configuration Errors: Incorrect settings in the RFC destination configuration (transaction SM59) can cause this error.
  Target System Unavailability: The target system may be down or not reachable due to maintenance or other issues.
