  Review Logs: Check the system logs (transaction SM21) for any errors or warnings that might provide more context about the issue.
  Restart Dispatcher: In some cases, restarting the dispatcher can resolve temporary issues. This can be done through transaction SM50 or SM66.
  Network Troubleshooting: If network issues are suspected, check the network configuration and connectivity between the application server and database server.
