Why did the change order fail on approval?

Open the History tab of the change order to review the sequence of actions on that change order. Depending on the action performed, the application displays a comment.

For example, if you try to promote two change orders simultaneously and the effective dates are less than 30 minutes apart, then a comment appears advising you to maintain a time difference of more than 30 minutes. You can also see the Workflow tab to review the change order status.
