This error can arise due to various reasons, including network issues, configuration problems, or authorization issues.
  Causes:
  
  Network Issues: There may be connectivity problems between the SAP system and the AS/400 system, such as firewalls blocking the connection or network outages.
  Configuration Errors: Incorrect RFC destination settings in the SAP system can lead to this error. This includes incorrect IP addresses, ports, or other connection parameters.
