Sales Order Qty Remaining

Is there a field on the Sales Order that shows the balance remaining on a Sales Order line? For example line 1 of the order has quantity of 10 but we shipped 7 already, is there a field that shows 3 remaining to be shipped? It seems like a basic field that should be available but I can’t seem to find it for a report.

Shipped from Inventory and Shipped from Job.

Which table is this in? I don’t see it in OrderDtl?
