  The SAP error message FCCX_MSG_S4036, which indicates an RFC scheduling error with the text "System Failure," typically points to issues related to Remote Function Call (RFC) communication between systems. This error can arise due to various reasons, including configuration issues, network problems, or system resource limitations.
  Possible Causes:
  
  Network Issues: Problems with the network connection between the SAP systems can lead to RFC errors.
  System Resource Limitations: Insufficient memory or CPU resources on the SAP application server can cause failures in processing RFC calls.
  Configuration Errors: Incorrect settings in the RFC destination or in the related configuration can lead to scheduling errors.
  System Locking: If the system is locked or undergoing maintenance, it may not be able to process RFC calls.
  Transport Layer Issues: Problems in the transport layer, such as issues with the SAP kernel or transport configuration, can also lead to this error.
  Authorization Issues: Lack of proper authorizations for the user or system making the RFC call can result in failures.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues between the systems involved. You can use tools like ping or traceroute to diagnose connectivity.
  Monitor System Resources: Check the system's memory and CPU usage. If resources are low, consider optimizing performance or scaling up the system.

  Check System Logs: Look into the system logs (transaction code SM21) and the developer trace files (transaction code ST22) for any additional error messages or clues.
  Restart Services: If the system is locked or unresponsive, restarting the relevant services or the entire system may resolve the issue.
