MRP#4 - No Safety Stock, No Stability: A Common Business Central MRP Planning Mistake

Without safety stock, MRP plans exactly to demand — which is rarely how real manufacturing works.

Why This Causes Problems

• No buffer for demand spikes

• No protection against supplier variability

• Over‑reaction to minor changes

What Safety Stock Actually Does

• Defines the planning “floor”

• Influences reorder points

• Improves ATP and CTP reliability

Practical Advice

• Use safety stock for volatile or long‑lead items

• Review it quarterly, not annually

• Don’t confuse safety stock with excess stock

Safety stock is not inefficiency — it’s controlled risk.
