1. SAP S/4HANA Help Portal - Sales Document Types: The official documentation for defining sales document types explicitly states that the sales document type controls key aspects of the sales process
including the proposed delivery type. In the configuration transaction VOV8 (Define Sales Document Types)
the "Delivery type" field (VTVAK-LIFAR) is located in the "Shipping" section
directly linking the sales document type to a default delivery type. (Source: SAP S/4HANA 2023 Product Assistance
