Which statement correctly differentiates between a sales order and a delivery document?

The statement that the sales order includes a header, line items, and schedule items is correct. In SAP S/4HANA, a sales order serves as a comprehensive document that captures essential information about the transaction. It includes a header section that contains general order information, line items that detail the specific products or services being sold, and schedule items that specify the delivery dates or quantities for those items.

This structure is crucial for managing sales processes, as it helps in tracking the details of the order through various stages, including fulfillment and invoicing. The inclusion of line items allows for a breakdown of the order into individual products or services, which is necessary for accurate order processing and inventory management.

In contrast, delivery documents, while important for logistics and shipping, mainly focus on the specifics of fulfilling the order rather than capturing all the detailed information present in a sales order. Understanding the distinctions between these two documents is vital for effectively managing sales and distribution processes within SAP.
