Report current quantity in all quotes

Report current quantity in all quotes

In our Deals (Potential) we issue Quotes for Products. I need to generate a report that shows me how many of each product is currently out on quote. I cannot seem to find a way to produce a report that shows the correct total if there are multiple units in some quotes.

Basically, I need help forecasting the number of products to keep in inventory based the Product SKU and Quantity of each SKU that is currently out on quote.
