To automatically create a delivery document immediately after saving a sales order, which customizing object must be activated?

The correct answer is related to the customization of the sales process in SAP S/4HANA. Specifically, the sales document type is crucial for automatically generating a delivery document immediately after saving a sales order.

This customization object defines the type of sales transaction and is integral in determining how the sales order will function within the broader sales and distribution process. By activating the specific sales document type, you can set the system to automatically create a delivery upon the successful creation of a sales order. This streamlines the order processing workflow by ensuring that the subsequent delivery activities are initiated without manual intervention.

In contrast, other objects like the sales organization, delivery type, and billing type serve different purposes in the process flow. The sales organization determines the structure and policies for sales operations, the delivery type defines how deliveries are processed, and the billing type is related to how invoices are created. While these elements are essential for overall system configuration, they do not directly control the automatic creation of delivery documents at the point of saving a sales order.
