Open Sales Order Reporting

SUGGESTED

Has anyone found a way to generate a report for Open Sales Orders that shows how much of an item is still open, or how much of the Sales Order total is still open?  For example, I have a Sales Order with 100 pcs, totaling $10,000.  50 of those pieces have been shipped, and only $5,000 of my sales order is still open.  The only reports I can find still show the entire $10,000 as being "open", and it looks like the entire order is still open instead of just half of it. 

Any help would be greatly appreciated!!
