Once you've uploaded the final report into Anow, delivered it to UWM, and there's no revisions required, you can mark the order as "Complete".
Go to the order details page (click on the order from your main dashboard).
Click the Mark Complete button at the top of the details page.
That's all there is to it. Now this order will appear in a completed status and it won't appear in your daily What's Happening email going forward.
