  title: Workday Finance Onboard Supplier and Raise Purchase Order
  summary: Resolve a supplier, confirm it is active, then raise a purchase order against it.
  description: >-
    A procure-to-pay starter flow. The workflow reads a supplier account to
    confirm it exists and is active, then creates a purchase order that
    references that supplier with one or more order lines, and finally reads the
    created purchase order back to confirm its status. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
