I'm designing a database to control an inventory of calibrated parts. The physical inventory is stored in drawers with compartments, each having a unique location number. I need to document where parts are used and when they need to be restocked. In the past, parts have been removed without their destination being documented.<br><br>I can easily require a destination field to be entered before a physical location is revealed. However, the technicians who routinely remove inventory will also be calibrating and restocking. Obviously, they will need a physical location number to do this. How can I prevent users from using the data entry form to obtain the location number and then removing parts without documentation.
