Which of the listed steps is NOT involved in determining the forwarding agent?

Determining the forwarding agent is a key process in sales and distribution within SAP S/4HANA, and it involves specific steps focused on partner determination and document management.

When it comes to assigning an order type, this step is generally related to the initial classification and processing of sales orders rather than the specific selection of a forwarding agent. The order type serves to define various administrative and processing parameters for sales documents but does not directly pertain to the actual identification of forwarding agents. Instead, any references for forwarding agents would arise from settings that explicitly relate to partner determination, document relevance, and copy control settings.

On the other hand, marking the forwarding agent as relevant for sales documents is a direct step indicating that the system should consider the forwarding agent in subsequent processes. Moreover, incorporating it into the partner determination procedure is essential because it establishes the rules for how partners, including forwarding agents, are identified based on various criteria in the sales document. Lastly, including relevant copy control settings is important for ensuring that necessary data and documents are carried over between different document types, but it doesn't directly influence who the forwarding agent is.

Thus, the correct answer highlights that assigning an order type does not play a role in the specific task of determining the forwarding agent.
