  title: Workday Review Supplier Spend
  summary: List suppliers, load the first supplier's detail, then review purchase orders and customer invoices.
  description: >-
    A procurement review flow. It lists suppliers and branches on whether any
    exist: when at least one is returned it loads the first supplier's detail,
    lists purchase orders, and lists customer invoices to build a spend picture,
    and when none are returned it ends. Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    description.
