What this feature does:
Added a new part active flag, "Drop Ship" Parts, to
1) Quick Pricing
2) Part Maintenance
Screen Shot 1: From Inventory Main Menu, choose "System Management", "Utilities", then
"Quick Pricing".
Notice the "Drop (X)" flag on the right of the screen.
Screen Shot 2: From "Part Maintenance", field "Active Flag:" now has the "X" option, for
"Drop Ship Parts".

Instructions:
Parts with an active flag set to "X" work the same as 'In-Stock Parts'.
Meaning, you can take orders for the items, but no backorders are allowed.
