  title: Workday Finance Reconcile Supplier Invoices
  summary: Confirm a supplier, list its outstanding invoices, then trace one back to its purchase order.
  description: >-
    An accounts payable reconciliation flow. The workflow reads a supplier to
    confirm it is active, lists supplier invoices filtered by status, branches
    on whether any were returned, and reads the originating purchase order of
    the first invoice to reconcile the two. Each step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
