For materials exclusively procured by consignment, what must be done for material requirements planning (MRP) to create consignment purchase requisitions?

For materials that are exclusively procured by consignment, it is essential to create at least one source of supply for consignment in order to facilitate the generation of consignment purchase requisitions within Material Requirements Planning (MRP). The sourcing process in SAP requires a defined source of supply to allow the system to recognize how to fulfill the material requirements.

In this context, the source of supply defines the agreement or the supplier that is providing the consigned materials, establishing the pathway for procurement activities. Without a designated source, MRP would not have the necessary information to create purchase requisitions, as it relies on source data to identify where materials can be sourced from and under what conditions.

In contrast, the other options focus on broader configurations and aspects of the material's procurement process that do not directly establish the fundamental requirement for consignment materials. For example, setting a standard procurement type or enabling automatic source determination may be beneficial, but they do not specifically address the need for an established source of supply for consignment to trigger MRP actions accurately. Adjusting the pricing procedure is also not relevant to ensuring that consignment purchase requisitions are generated correctly, as it pertains more to financial transactions rather than sourcing logistics.
