Define the types of items and the quantities that can be stored in the replenishment, or forward-pick locations typically. Picking functions look in these locations first before searching the rest of the warehouse for available inventory.

In QMI data, there is a bulk reserve, a case pick area, and an each pick area, as shown above.

Bulk Reserve storage is for larger unit loads (pallets) and designed to optimize space.

Case and Each picks are for smaller item quantities and designed to optimize handling.
