• What is the cause and solution for SAP error message BGRFC458 - Server &1: Configured inbound schedulers &2, currently available &3 ?

  The SAP error message BGRFC458 indicates an issue with the background RFC (BGRFC) configuration, specifically related to the availability of inbound schedulers. This error typically arises when the system is unable to find an available inbound scheduler to process the BGRFC requests.
  Cause:
  
  
  Scheduler Configuration: The error suggests that the configured inbound schedulers are either not active or not available. This could be due to:
  
  The inbound scheduler not being started.
  The number of available schedulers being less than the configured number.
  Network issues or system resource constraints affecting the scheduler's availability.
  
  
  
  System Load: High system load or resource contention can lead to the unavailability of the inbound schedulers.
  
  
  Transport Layer Issues: If there are issues in the transport layer or if the BGRFC is not properly configured, it can lead to this error.
  
  
  Solution:
  
  
  Check Inbound Scheduler Status:
  
  Use transaction code SM58 to check the status of the BGRFC queues and see if there are any stuck or failed entries.
  Use transaction code SM21 to check the system log for any related errors.
  
  
  
  Start Inbound Schedulers:
  
  Ensure that the inbound schedulers are properly configured and started. You can check the configuration in transaction SMQS (for BGRFC) and ensure that the inbound queues are active.
  
  
  
  Adjust Configuration:
  
  If the number of configured inbound schedulers is too high compared to the available ones, consider adjusting the configuration to match the available resources.
  
  
  
  Monitor System Resources:
  
  Check system performance and resource utilization (CPU, memory, etc.) to ensure that the system is not overloaded.
  
  
  
  Review Network Configuration:
  
  Ensure that there are no network issues affecting the communication between the systems involved in the BGRFC.
  
  
  
  Restart the System: If the issue persists, consider restarting the SAP system or the relevant application servers to reset the state of the schedulers.
  
  
  Related Information:
  
  BGRFC: Background Remote Function Call is a mechanism in SAP that allows asynchronous communication between different SAP systems or between different application servers within the same system.
  Transaction Codes:
  
  SMQS: Monitor BGRFC queues.
  SM58: Monitor transactional RFC (tRFC) queues.
  SM21: System log for error messages.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to BGRFC and inbound scheduler configurations.
  
  If the problem continues after following these steps, it may be necessary to consult with SAP support or your system administrator for further investigation.
