If needed to remove large amounts of inventory that were added possibly in error
the physical count adjustment is a useful function to accomplish that task.
The physical count adjustment can be found from the Functions menu once in Inventory
or in the POS interface option B from the menu
For example if 10 items were added of an item, and it should have been only 1 item, you can use the physical count adjustment
and enter the correct amount in the count field
The physical count adjustment does not allow for adjusting serialized items, or bulk items.
Another way to remove items is opening the inventory item using the quantities menu
choosing remove item, unfortunately that only removes one of the item.
