Adjustment: Inventory balances in perpetual inventory systems should be verified periodically by a physical count of the items on hand. Any discrepancy between the system value of the inventory and the cost of the actual quantity on hand must be recorded in the general ledger. Adjustments may also be entered for other reasons, such as theft or damaged goods. An adjustment updates inventory data only. It is used to change a warehouse item's on-hand balance or unit cost.
Issue: An issue updates inventory data and may also update resource demand, work order cost, and asset cost data.
Inventory Return: An inventory return updates inventory data and may also update resource demand, work order cost, and asset cost data.
Invoice: An invoice updates resource demand.
Transfer: A transfer updates inventory data for the transferring (i.e., transfer from) warehouse, and may also update resource demand.
Transfer Receipt: A transfer receipt updates inventory data for the receiving (i.e., transfer to) warehouse.
Timecard: A timecard updates work order cost and asset cost data.
