After you click Start ETL refresh Under Refresh data on the Reporting data mart page, the ETL refresh status page appears. The Start ETL refresh task manually starts the ETL process independent of any job schedules and updates the data mart with data that was added or modified in the source database since the previous ETL refresh. On the ETL refresh status page, you can view information about the ETL process as it runs.
The page displays the job name, current ETL status, whether the process was completed successfully, the date, and how long the process has run. Under Status log, a log appears for the ETL process. You can use this log to check the status and to troubleshoot if a problem occurs during the process.
