  title: Tango Vendor One-to-Many Inbound — File
  version: '0.4'
  description: |
    SFTP file-based inbound for clients where one supplier has many sites.
    Each pipe-delimited row carries BOTH supplier-level fields
    (`Supplier_number`, `Supplier_name`, `Supplier_Status`,
    `Supplier_Address1..3`, etc.) AND site-level fields
    (`Supplier_Site_Number`, `supplier_site_name`, `address_1..3`, etc.).

    Multiple rows with the same `Supplier_number` represent multiple sites
    for that supplier. Same SFTP path (`/inbound/vendor`) and naming
    convention as the standard Vendor file — Tango disambiguates by file
    content shape.
