Purchasing uses Oracle Workflow technology to handle requisition and purchase order approvals, automatic creation of purchase orders and releases, purchase order changes (specifically, any additional approvals those changes require), notifications, and receipt confirmation. Workflow is an underlying technology that automates these procurement activities. Workflow comes with a graphical user interface that enables you to modify these procurement workflow processes to suit your business needs.
Purchasing comes with the following workflows:
PO Account Generator workflow for automatically generating accrual, budget, charge, and variance accounts on purchase orders and releases. See: Using the Account Generator in Oracle Purchasing.
PO Requisition Account Generator workflow for automatically generating accrual, budget, charge, and variance accounts on requisitions. See: Using the Account Generator in Oracle Purchasing.
PO Requisition Approval workflow for approving requisitions. See: Requisition Approval Workflow.
