Understand where orders "go", and how to process all the way through.
If you'd like to check up on an order and see what processes have been completed during the In Progress stage, you can view the progress on the order page under order info in the sidebar.
Click on the More drop down under the order status, then click on Show History to see which stages have been completed or are currently in progress. You can still view this after the order has shipped by going to the Resource Allocation tab of the order and following the same steps.
