• What is the cause and solution for SAP error message BGRFC453 - Number of units executed in the last five minutes: &2 (&1) ?

  The SAP error message BGRFC453 indicates that there is an issue with the background RFC (BGRFC) processing in the SAP system. Specifically, this message is related to the number of units executed in the last five minutes exceeding a predefined threshold. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  High Load: The system is experiencing a high load of background RFC calls, which may be due to a large number of asynchronous processes being executed in a short period.
  Configuration Limits: The system may have configuration limits set for the number of BGRFC units that can be processed in a given timeframe.
  Performance Issues: There may be performance bottlenecks in the system, such as slow database access or resource contention, leading to delays in processing BGRFC calls.
  Network Issues: Network latency or connectivity issues can also contribute to delays in processing BGRFC calls.
  
  Solution:
  
  Monitor BGRFC Queue: Use transaction code SM58 to monitor the BGRFC queue and identify any stuck or failed calls. This can help in diagnosing the issue.
  Adjust Configuration: If the number of units executed is consistently high, consider adjusting the configuration settings for BGRFC. This can be done in transaction RZ10 or RZ11 to change parameters related to BGRFC processing.
  Performance Tuning: Analyze the performance of the system and optimize any slow-running processes. This may involve database tuning, optimizing ABAP code, or increasing system resources (CPU, memory).
  Increase Processing Capacity: If the system is regularly hitting the limits, consider increasing the processing capacity by adding more application servers or adjusting the load balancing settings.
  Check for Errors: Review the system logs (transaction SM21) and BGRFC logs (transaction SLG1) for any errors that may provide additional context on the issue.
  Restart BGRFC: In some cases, restarting the BGRFC processing can help clear any temporary issues. This can be done using transaction SMQ1 for outbound queues.
  
  Related Information:
  
  BGRFC Overview: Background RFC (BGRFC) is a mechanism in SAP that allows for asynchronous communication between different SAP systems or between different application servers within the same system.
  Monitoring Tools: Use tools like ST22 for dumps, SM37 for job monitoring, and ST03N for workload analysis to get a comprehensive view of system performance.
  SAP Notes: Check for relevant SAP Notes that may address specific issues related to BGRFC processing or performance tuning.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with SAP support or your system administrator for further assistance.
