What does it mean for the production planner when MRP operates with infinite capacities?

When MRP operates with infinite capacities, it essentially means that the system does not impose any limitations on the capacity of work centers when planning production. This scenario allows MRP to generate planned orders and capacity requirements based solely on demand and inventory levels, without having to validate whether the work centers have enough capacity to handle these demands.

In this context, MRP focuses on fulfilling product requirements as they arise, creating plans that depict an ideal scenario where resources are unlimited. This can lead to a planning environment where orders are created, regardless of whether the actual capacity exists to fulfill them, thus making it crucial for production planners to later analyze these requirements and prioritize scheduling activities accordingly.

With this working principle, the planner must subsequently account for real-world constraints and capacity limitations, as the MRP outputs might not be immediately feasible.
