MB-330 Implement Master Planning Practice Question
A company uses Master Planning with a dynamic plan. The planning run is configured to include purchase orders with a status of 'Confirmed' and 'Received'. A planner notices that a confirmed purchase order for 100 units of an item does not reduce the net requirement in the planned orders. Which configuration is most likely causing the confirmed purchase order to be ignored by the planning run?
⚠ Common exam trap
The trap here is blaming plan-level or coverage settings for an order-specific exclusion, when the 'Include in master planning' flag on the purchase order itself is the decisive control.
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
✓
The purchase order's 'Include in master planning' field is set to No.
Master Planning nets supply against demand using orders that are marked as included in master planning. A confirmed purchase order whose 'Include in master planning' field is set to No is invisible to the planning engine, so the requirement remains and planned orders are created. Setting the flag back to Yes restores the expected netting behavior.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The purchase order's 'Include in master planning' field is set to No.
Why this is correct
The 'Include in master planning' flag on the purchase order header controls whether that order is considered as supply during the planning run. If it is set to No, the confirmed 100 units are excluded from net requirement calculation, so Master Planning generates additional planned orders for the full demand even though supply exists.
- ✗
The item's coverage group has a negative days setting of 0.
Why it's wrong here
Negative days define how far back the system looks for demand when calculating coverage, not whether firm supply is included. A value of 0 simply means no negative-day offset; it does not exclude confirmed purchase orders from the net requirement calculation, so this setting would not cause the supply to be ignored.
- ✗
The master plan's 'Include purchase orders' option is disabled.
Why it's wrong here
The master plan does not have a single global 'Include purchase orders' toggle that overrides individual order flags. Purchase order inclusion is governed per order via the 'Include in master planning' field, so disabling a plan-level option is not the mechanism that would exclude this specific confirmed purchase order.
- ✗
The purchase order's delivery date is before the plan's coverage time fence.
Why it's wrong here
A delivery date inside the coverage time fence affects how demand within that horizon is treated, but it does not remove the order from supply. The confirmed purchase order would still be counted as expected receipt unless its inclusion flag is turned off, so the date alone would not explain the missing netting.
