Where can consumption mode and periods for planning strategies be maintained?

Consumption mode and periods for planning strategies are primarily maintained in the material master. The material master serves as a central repository of information related to materials used in the organization, including attributes that influence planning and consumption behavior. Specifically, within the material master, the planning data section provides the necessary fields to set up the consumption mode and define the periods associated with various planning strategies. This allows companies to tailor their inventory management and production planning processes to meet specific operational needs.

The other options, while related to planning and management, do not specifically house the consumption modes and periods. For instance, the requirements class is more focused on controlling how requirements for materials are handled, including planning and procurement processes. Similarly, the MRP group is utilized for grouping materials with similar planning requirements but does not directly address consumption settings. Lastly, the plant parameters provide configuration settings that influence the overall planning process, yet they do not specifically encompass the detailed consumption settings found in the material master.
