  title: Oracle EBS Requisition-to-Purchase-Order
  summary: Find an approved requisition, resolve its supplier, and convert it into a purchase order.
  description: >-
    An Oracle Purchasing flow that turns demand into a buy. The workflow locates
    an approved purchase requisition, resolves the intended supplier by name,
    creates a standard purchase order for the requested item, and reads the
    order back to confirm it. Each step inlines its request so the
    requisition-to-PO chain can be executed without opening the OpenAPI source.
