Adjust the quantity of an item in a particular bin or bins. For instance, you might find some items in a bin that are not registered in the system, or you might not be able to pick the quantity needed because there are fewer items in a bin than was calculated by the program. The bin is then updated to correspond to the actual quantity in the bin. In addition, it creates a balancing quantity in the adjustment bin, for synchronization with item ledger entries, which you can then post with an item journal.
