MB-330 Implement Master Planning Practice Question
A manufacturer runs Master Planning for a product that is purchased from a vendor with a confirmed lead time of 14 days. The planning run currently generates planned purchase orders with a lead time of 7 days, causing material shortages. Which item coverage setting must be reviewed and corrected to align the planning run with the vendor's actual lead time?
⚠ Common exam trap
The trap here is assuming that safety stock or a coverage time fence can substitute for a long procurement lead time, when only the lead time setting actually shifts the planned order date.
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
✓
Lead time = 14 in the Default order settings
Master Planning back-schedules planned purchase orders using the purchase lead time defined on the item's Default order settings. Because the vendor requires 14 days but the item is configured with 7, every planned order is created too late. Correcting the lead time to 14 days makes the planning engine place order dates correctly and eliminates the material shortages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Coverage time fence = 14
Why it's wrong here
The coverage time fence limits how far ahead the coverage calculation looks for demand; it does not set the procurement lead time. A 14-day time fence would expand the demand horizon but the planned purchase order would still be scheduled using the 7-day lead time, leaving the shortage unresolved.
- ✗
Safety stock = 14
Why it's wrong here
Safety stock is an extra quantity buffer held to absorb demand variability, not a time offset. Entering 14 as safety stock would increase inventory levels but would not change the order date calculation, so planned purchase orders would still be created only 7 days before the requirement date.
- ✓
Lead time = 14 in the Default order settings
Why this is correct
The purchase lead time on the item's Default order settings is the value Master Planning uses to back-schedule planned purchase orders from the requirement date. Setting it to 14 days aligns the generated planned order dates with the vendor's confirmed lead time and prevents the shortages caused by the current 7-day assumption.
- ✗
Coverage code = Min/Max
Why it's wrong here
The coverage code determines the replenishment strategy, such as Min/Max or Period, but it does not define the procurement lead time used to back-schedule planned orders. Changing the coverage code alone would not extend the 7-day lead time to 14 days, so the shortages caused by the shorter lead time would persist.
