• What is the cause and solution for SAP error message BGRFC028 - Unit &1 started by &2 in debugger ?

  The SAP error message BGRFC028 indicates that a background RFC (Remote Function Call) unit has been started in the debugger. This typically occurs when a background job is executed in a way that triggers the debugger, which can happen for various reasons, such as an unhandled exception or a breakpoint being set in the code.
  Cause:
  
  Breakpoint in Code: A breakpoint may have been set in the ABAP code that is being executed in the background job.
  Debugging Mode: The system might be running in debugging mode, which can cause background jobs to trigger the debugger.
  Unhandled Exceptions: An unhandled exception in the code can lead to the debugger being invoked.
  Configuration Issues: There may be issues with the configuration of the background job or the RFC destination.
  
  Solution:
  
  
  Check for Breakpoints: 
  
  Go to the ABAP editor (transaction SE80 or SE38) and check if there are any breakpoints set in the code that is being executed. Remove any unnecessary breakpoints.
  
  
  
  Disable Debugging Mode: 
  
  Ensure that the system is not running in debugging mode. You can check this in the user settings or by using transaction SE38 and executing the program with the debugger turned off.
  
  
  
  Handle Exceptions: 
  
  Review the code for any unhandled exceptions. Implement proper exception handling to prevent the debugger from being triggered.
  
  
  
  Check Job Configuration: 
  
  Review the configuration of the background job (transaction SM37) to ensure that it is set up correctly and that the RFC destination is properly configured.
  
  
  
  Use Transaction SM50/SM66: 
  
  Monitor the work processes using transaction SM50 (for local instance) or SM66 (for global instance) to see if there are any stuck processes or issues with the background job.
  
  
  
  Review Logs: 
  
  Check the job logs and system logs (transaction SM21) for any additional error messages or warnings that could provide more context about the issue.
