Understanding Quantity Information

Quantity information includes the available and on-hand quantities for items. You use quantity information to determine the current and future inventory needs. This table lists the types of quantity calculations the system performs:

Calculation	Description
Days available	Reflects the number of days in the future that an item will be available.
On-hand	Reflects the total number of items in a particular branch/plant.
Commitments	This calculation includes soft commitments, hard commitments, and quantities on work orders.
Available	Defines how the system performs this calculation. Typically, it includes on-hand quantities minus any outstanding commitments, reservations, and backorders.
On receipt	Reflects quantities that are on open purchase orders.
Reorder point	Specifies the minimum item quantity for which replenishment should occur, or you can have the system calculate it.
Economic Order Quantity (EOQ)	Determines a minimum quantity for an item based on an economic analysis of the cost of placing an order and keeping inventory.
