• What is the cause and solution for SAP error message /SAPPSPRO/_NO_RFC002 - System failure ?

  The SAP error message /SAPPSPRO/_NO_RFC002 System failure typically indicates a problem with the Remote Function Call (RFC) communication between SAP systems or between an SAP system and an external system. This error can arise due to various reasons, including configuration issues, network problems, or system resource limitations.
  Causes:
  
  Network Issues: Problems with the network connection between the SAP systems can lead to RFC failures.
  Configuration Errors: Incorrect settings in the RFC destination configuration (transaction SM59) can cause communication failures.
  System Resource Limitations: Insufficient memory or CPU resources on the SAP application server can lead to system failures.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations.
  System Lock: The target system may be locked or down for maintenance, leading to communication failures.
  Transport Layer Issues: Problems with the transport layer or middleware can also cause RFC errors.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there is proper network connectivity between the systems involved. You can use tools like ping or traceroute to diagnose network issues.
  Review RFC Destination Configuration: Go to transaction SM59 and check the configuration of the RFC destination. Ensure that the connection parameters (like target host, system number, client, user, and password) are correct.
  Monitor System Resources: Use transaction SM50 or SM66 to monitor the system's performance and check for any resource bottlenecks. If necessary, increase the resources allocated to the SAP system.
  Check Authorizations: Verify that the user credentials used for the RFC connection have the necessary authorizations to perform the required actions.
  Check System Status: Ensure that the target system is up and running. You can check the status of the system using transaction SM51 to see if the instance is active.
  Review Logs: Check the system logs (transaction SM21) and the developer trace files (transaction ST11) for any additional error messages or warnings that could provide more context about the failure.
  Restart Services: If the issue persists, consider restarting the affected SAP services or the entire SAP system if feasible.
