• What is the cause and solution for SAP error message FVD_EXP020 - Error during RFC call - no free resources available ?

  The SAP error message FVD_EXP020 indicates that there was an error during a Remote Function Call (RFC) due to a lack of available resources. This typically occurs when the system is unable to allocate the necessary resources to process the RFC request, which can be caused by various factors.
  Causes:
  
  System Resource Limitations: The SAP system may be running low on memory, CPU, or other resources, leading to an inability to handle additional RFC calls.
  High Load: A high volume of concurrent RFC calls can exhaust the available resources, especially if the system is under heavy load.
  Configuration Issues: Incorrect configuration settings for the RFC destination or the SAP system can lead to resource allocation problems.
  Network Issues: Network latency or connectivity issues can also contribute to the inability to process RFC calls.
  Locks or Deadlocks: If there are locks or deadlocks in the system, it may prevent the processing of new requests.
  
  Solutions:
  
  Monitor System Resources: Use transaction codes like SM50 (Process Overview) and SM66 (Global Work Process Overview) to monitor the system's resource usage. Check for any long-running processes or bottlenecks.
  Increase Resources: If the system is consistently running low on resources, consider increasing the hardware resources (CPU, memory) allocated to the SAP system.
  Adjust Configuration: Review and adjust the configuration settings for the RFC destination in transaction SM59. Ensure that the settings are optimized for your environment.
  Limit Concurrent Calls: If possible, limit the number of concurrent RFC calls being made to the system to reduce the load.
  Check for Locks: Use transaction SM12 to check for any locks that may be causing issues. If necessary, release any unnecessary locks.
  Review Logs: Check the system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the issue.
  Network Troubleshooting: If network issues are suspected, perform network diagnostics to ensure that there are no connectivity problems between the systems involved in the RFC call.
