  title: SAP S/4HANA Sales Order Partners API
  description: The SAP S/4HANA Sales Order API (API_SALES_ORDER_SRV) enables you to create, read, update, and delete sales orders in SAP S/4HANA. This OData V2-based service provides access to complete sales order documents including header data, line items, pricing elements, schedule lines, partners, and text records. It supports deep insert operations for creating a sales order header with its dependent entities in a single request. The API covers the full sales order lifecycle from creation through to completion and rejection.
