  title: Business Central Create a Purchase Invoice for a Vendor
  summary: Resolve a vendor by number, draft a purchase invoice, and confirm it landed.
  description: >-
    An accounts-payable entry flow for Business Central. The workflow resolves a
    vendor by their number to obtain the vendor id, creates a draft purchase
    invoice bound to that vendor, and then lists purchase invoices filtered to
    the new invoice number to confirm the document landed. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
