• What is the cause and solution for SAP error message FRE168 - RFC-Error: Resource Failure - Sequential Processing ?

  The SAP error message FRE168, which indicates an RFC (Remote Function Call) error due to "Resource Failure - Sequential Processing," typically arises in scenarios where there are issues with the processing of requests in a sequential manner. This can occur in various contexts, such as when using background jobs, batch processing, or when multiple requests are being processed in a sequence.
  Causes:
  
  Resource Limitations: The system may be running out of resources (e.g., memory, CPU, or network bandwidth) to handle the requests sequentially.
  Locking Issues: If a resource is locked by another process, it can lead to failures in sequential processing.
  Configuration Issues: Incorrect configuration of the RFC destination or the system settings can lead to this error.
  Network Issues: Problems with the network connection between the systems involved in the RFC call can cause failures.
  Timeouts: If the processing takes too long, it may exceed the timeout settings, leading to a failure.
  
  Solutions:
  
  Check System Resources: Monitor the system's resource usage (CPU, memory, etc.) and ensure that there are sufficient resources available. You may need to optimize the workload or increase the resources.
  Review Locks: Use transaction codes like SM12 to check for locks that may be causing the issue. If necessary, release locks that are no longer needed.
  Adjust Configuration: Verify the configuration of the RFC destination in transaction SM59. Ensure that the settings are correct and that the destination is reachable.
  Network Troubleshooting: Check the network connectivity between the systems. Ensure that there are no firewalls or network issues that could be causing interruptions.
  Increase Timeout Settings: If the processing is taking too long, consider increasing the timeout settings in the RFC configuration.
  Review Logs: Check the system logs (transaction SM21) and the application logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the failure.
