This has always been a question for me.  Why even have a field for number of sheets if there is no functionality that uses it?  Or is this one of those issues where, if you buy another module, it can be made to work?  I hope not.  Theoretically, one would think that the field is there so you can input your inventory, and at least be notified when you run out, or, even better, be given the opportunity to use another sheet size if you run out of the ideal size.  Does anybody know if MV has ever, or intends to address this?
