Article • 7/21/2025 • 3 min read

A Blanket Purchase Order (Blanket PO) allows you to take advantage of price breaks and terms by agreeing to a larger order quantity to be delivered in smaller increments over a set length of time as agreed with your vendor. It is normally used when there is a recurring need for the materials and supplies consumed regularly.

It is only used by the Planning and Scheduling modules for adding releases based on the Planned Purchase Orders in thePlanned Purchase Queue (PLNPOQ) page.
