  Check for Locks: Use transaction code SM12 to check for any locks that might be affecting the BgRFC processing. If you find any unnecessary locks, you can release them.
  Increase Resources: If the system is under heavy load, consider increasing the resources allocated to the application server or optimizing the existing processes.
  Network Connectivity: Ensure that there are no network issues affecting communication between systems. Check firewalls, network configurations, and connectivity.
  Review Logs: Check the application logs for any additional error messages or warnings that might provide more context about the issue. Use transaction code SLG1 to view logs related to the OData service.
