  title: Oracle EBS Procure-to-Pay
  summary: Resolve a supplier, raise a purchase order, confirm it, then record the matching AP invoice.
  description: >-
    A core Oracle E-Business Suite buy-side flow. The workflow first locates an
    approved supplier by name, creates a standard purchase order against that
    vendor, reads the created order back to capture its header identifier, and
    finally books an Accounts Payable invoice referencing the same vendor and
    amount. Each step inlines its request so the procure-to-pay chain can be
    read and executed without opening the underlying OpenAPI descriptions.
