Purchase Orders Types in Oracle R12Oracle Purchasing supports four types of purchase orders:
Standard Purchase Orders:
You generally create standard purchase orders for one-time purchase of various items. You create standard purchase orders when you know the details of the goods or services you require, estimated costs, quantities, delivery schedules, and accounting distributions.
Blanket Purchase Agreements:
You create blanket purchase agreements when you know the detail of the goods or services you plan to buy from a specific supplier in a period, but you do not yet know the detail of your delivery schedules. In this case you create and use blanket purchase agreements to specify negotiated prices for your items before actually purchasing them.
Contract Purchase Agreements:
You create contract purchase agreements with your suppliers to agree on specific terms and conditions without indicating the goods and services that you will be purchasing. You can later issue standard purchase orders referencing your contract.
Planned Purchase Order:
You create a planned purchase order when you want to establish a long term agreement with a single source supplier with a commitment to buy goods or services. Planned purchase orders include tentative delivery schedules and accounting distributions.
