SAP Business One Purchasing

SAP Business One is an enterprise resource planning (ERP) solution designed for small and midsize businesses by SAP SE. The ballerinax/sap.businessone.purchasing connector exposes the purchasing (A/P) documents of SAP Business One — purchase requests, quotations, orders, goods receipts, returns, invoices, and landed costs — through the SAP Business One Service Layer (OData) API. Authentication uses the Service Layer session protocol, with automatic re-login when a session expires.

  • Raise purchase requests and purchase quotations
  • Manage purchase orders and goods receipt POs (purchase delivery notes)
