What must you include in the partner determination procedure for a sales document type related to the forwarding agent?

In a partner determination procedure for a sales document type, including the forwarding agent partner function is essential because it explicitly designates the role of the forwarding agent in the sales process. The forwarding agent is responsible for the transportation and logistics of goods from the seller to the buyer, making their inclusion vital for effective management of shipments.

When the forwarding agent partner function is included, it ensures that relevant information such as contact details and responsibilities for the movement of goods is accessible during order processing and shipment tracking. This facilitates better communication and coordination between the seller and the logistics provider, leading to seamless execution of the sales order.

The other elements mentioned, such as shipping point assignment, sold-to party assignment, and route determination, play roles in different aspects of the sales and distribution process but do not specifically pertain to the role of the forwarding agent in the partner determination procedure. Shipping point assignment relates to the physical locations from where goods are dispatched, sold-to party assignment identifies the actual buyer in the transaction, and route determination focuses on calculating the best route for the delivery process. While these components are critical for the overall operation, the specific need for the forwarding agent's role makes option B the most relevant to partner determination in this context.
