Inventory Adjustment, on the line items, how can you remove Adjust Qty. By as a required field? when you click the Inventory Detail icon, and enter in the serial lot numbers, status, and quantities there....we want the sum of those Quantities of the line items in the Standard Inventory Detail Form to populate in the "Adjust Qty By" field instead.

There is suiteanswer that shows you how to import, I am guessing you either use lot/serial number or bins

You either have to import, where you still have to map the adj. Qty by field, or script this for the UI
