Database limits

For certain applications, after a refresh is scheduled, the request is evaluated. This step is known as DB Limits, and it evaluates the refresh request for potential issues that can cause the refresh to fail. If any issues are identified during the DB Limits evaluation, the refresh is canceled, and you receive a notification.

A refresh scheduled for a future date is evaluated a second time forty-eight hours before the scheduled launch time to ensure no issues emerged after the first evaluation. The refresh is then evaluated a third time immediately prior to the launch. If you schedule a refresh to launch immediately, then there is only one evaluation.
