• What is the cause and solution for SAP error message BGRFC668 - Average time of a bgRFC unit in the runnable table ?

  The SAP error message BGRFC668 indicates that the average time of a bgRFC (Background Remote Function Call) unit in the runnable table has exceeded a certain threshold. This can be a sign of performance issues in the bgRFC processing, which can lead to delays in processing background tasks.
  Cause:
  
  High Load: The system may be experiencing a high volume of bgRFC calls, leading to longer processing times.
  Resource Bottlenecks: Insufficient system resources (CPU, memory, I/O) can slow down the processing of bgRFC units.
  Long-running Transactions: Some bgRFC units may be taking longer to execute due to complex processing or locking issues.
  Configuration Issues: Incorrect configuration of bgRFC settings or parameters may lead to inefficiencies.
  Network Latency: If bgRFC calls involve remote systems, network issues can contribute to delays.
  
  Solution:
  
  Monitor bgRFC Performance: Use transaction SM58 to monitor the status of bgRFC calls and identify any that are taking too long.
  Analyze System Performance: Check system performance metrics (CPU, memory, I/O) using transaction ST03N or ST06 to identify any bottlenecks.
  Optimize Long-running Transactions: Review and optimize the code of any long-running bgRFC units to improve their execution time.
  Adjust bgRFC Configuration: Review and adjust bgRFC configuration settings in transaction SICF or RZ10 to optimize performance.
  Increase Resources: If the system is under heavy load, consider increasing hardware resources or optimizing existing workloads.
  Check for Locks: Use transaction SM12 to check for any locks that may be affecting bgRFC processing.
  Review Network Performance: If applicable, check network performance and latency between systems involved in bgRFC calls.
  
  Related Information:
  
  bgRFC Overview: bgRFC is a mechanism in SAP for asynchronous communication between different SAP systems or between different processes within the same system.
  Transaction Codes:
  
  SM58: Monitor and manage asynchronous RFC calls.
  SICF: Configuration of Internet Communication Framework services.
  RZ10: Profile parameters for system configuration.
  ST03N: Workload analysis and performance monitoring.
  SM12: Monitor and manage locks in the system.
  
  
  SAP Notes: Check for relevant SAP Notes that may provide additional insights or patches related to bgRFC performance issues.
  
  By following these steps, you should be able to identify the root cause of the BGRFC668 error and implement appropriate solutions to mitigate the issue.
