MB-330 Implement Master Planning Practice Question
You are setting up Master Planning for a company that wants to include safety stock in their planning. They want to ensure that Master Planning suggests replenishment when inventory falls below a certain threshold, even if there is no immediate demand. Which coverage code should you use to achieve this?
⚠ Common exam trap
The trap here is thinking that safety stock is only configured in the coverage group's safety stock field, but the Min/Max coverage code uses the minimum as the trigger for replenishment, effectively serving as safety stock.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Min/Max
Min/Max coverage code is designed to maintain inventory between a minimum and maximum level. When inventory drops below the minimum, Master Planning creates a planned order to bring it back up to the maximum. This inherently includes safety stock because the minimum acts as the safety stock threshold. The other coverage codes are demand-driven and do not automatically replenish to a threshold without demand.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Min/Max
Why this is correct
Min/Max coverage code allows you to set a minimum inventory level (safety stock) and a maximum level. Master Planning will create planned orders when inventory falls below the minimum, ensuring safety stock is maintained. This directly meets the requirement to replenish when inventory falls below a threshold, even without immediate demand.
- ✗
Requirement
Why it's wrong here
Requirement coverage code generates planned orders based on actual demand, such as sales orders or production orders. It does not consider safety stock thresholds. Therefore, it would not suggest replenishment when there is no demand, even if inventory is low. This does not meet the company's need for safety stock planning.
- ✗
Manual
Why it's wrong here
Manual coverage code disables automatic planned order creation. The company would have to manually create orders to maintain safety stock, which is not what they want. Master Planning would not suggest replenishment automatically, so this does not meet the requirement.
- ✗
Period
Why it's wrong here
Period coverage code aggregates demand over a specified period and creates planned orders to cover net requirements. It does not explicitly maintain a safety stock level. While you can include safety stock in the coverage settings, the Period code itself is demand-driven and would not trigger replenishment solely based on a threshold without demand.
