What effect does changing the MRP type of a material have?

Changing the MRP type of a material primarily affects the material’s planning frequency. The MRP (Material Requirements Planning) type dictates how a material is managed in terms of inventory and replenishment strategies. Each type defines specific requirements and rules that determine how often a material is planned and monitored, which can include considerations for lead times, stock requirements, and procurement strategies.

For instance, a material with a planning type that supports MRP will have more frequent evaluations for inventory levels and generate purchase or production proposals based on demand forecasts. Conversely, materials that are planned less frequently may not receive updates as often, affecting how stock levels align with actual demand over time.

In contrast, while inventory levels might be influenced indirectly by the changes in MRP type, they are not directly determined by the MRP type itself. The procurement process can also be influenced, but that is more a result of the overall planning strategy rather than a direct consequence of changing just the MRP type. Scheduled manufacturing times are typically fixed and not directly modified through changes in the MRP type, as they relate to production capacity and lead time rather than planning frequency.
