Interdependencies between PO, IC, and AP

Purchase Order interfaces closely with two other applications, namely Inventory Control and Accounts Payable. For example, Purchase Order receives vendor information from Accounts Payable and item/reorder information from Inventory Control.

Because of this interface, sometimes changing setup options midstream in Inventory Control and Accounts Payable applications affects the Purchase Order application as well. For example, changing an item's unit of measure when existing transactions still use the old unit of measure can cause processing issues in the Purchase Order application. Also, if you inactivate a vendor (or vendor location) in the Accounts Payable application, you can no longer create a purchase order using that vendor (or vendor location) in the Purchase Order application.
