Use Inventory
If set to TRUE, able to use Purchase Orders, Receipts, view Inventory Status, make Inventory Adjustments, and request order of Parts within service workorders.
If set to FALSE, only able to enter Parts, and select Parts without affecting inventory.
NOTE: Changing Use Inventory to False, entering a quantity of parts in workorders, and changing Use Inventory back to True can result in on-hand amounts becoming out of synch as inventory is not tracked when set to False. If you do this, you may need to make Inventory Adjustment entries to adjust for the inconsistencies of parts entered in workorders where inventory tracking was not in use.
