Blanket purchase orders

Blanket purchase orders (POs) are used to communicate contractual terms for a given time period. They contain header information and line item details that formally state all the terms and conditions of the transaction, including quantity due, PO expiration date, price, and other associated costs. Customers then use one of the part ordering systems in Supplier Exchange (Schedules, Purchase Orders, Supplier Managed Inventory, or Kanban) to order specific quantities with a specific requirement date.
