• What is the cause and solution for SAP error message BGRFC124 - Unit &1 is being debugged ?

  The SAP error message BGRFC124 indicates that a background RFC (Remote Function Call) unit is currently being debugged. This typically occurs when a background RFC process is halted due to a debugging session being active, which prevents the process from executing as expected.
  Cause:
  
  Debugging Session Active: The most common cause of this error is that a developer or administrator has started a debugging session on the background RFC unit, which locks the unit and prevents it from being processed.
  Long-Running Processes: If a background job is taking too long and is being debugged, it can lead to this error.
  Configuration Issues: There may be configuration issues in the system that lead to unexpected behavior in background processing.
  
  Solution:
  
  End Debugging Session: If you are debugging the background RFC unit, you need to end the debugging session. You can do this by stopping the debugger in the ABAP development environment.
  Check for Active Debugging: Use transaction SM50 or SM66 to check if there are any active debugging sessions. If you find one, you can terminate it.
  Review Background Jobs: Check the background jobs that are running using transaction SM37. Look for any jobs that might be stuck or in a long-running state.
  Restart the Job: If the job is stuck, you may need to cancel it and restart it after ensuring that no debugging sessions are active.
  System Configuration: If the issue persists, review the system configuration related to background processing and RFC settings to ensure everything is set up correctly.
