MB-330 Implement Master Planning — 30 Questions

Question 1

A company uses coverage groups to manage replenishment. You need to ensure that the Master Planning process ignores demand that occurs before the current date to prevent legacy orders from impacting supply suggestions. Which parameter should you configure?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Set the Negative days to 0.. The 'Negative days' parameter in the coverage group defines the time fence for fulfilling shortages. By setting negative days to zero, the system forces the creation of new supply orders for any demand that is past due or due today, rather than attempting to cover it with existing inventory or late receipts. This is critical for maintaining clean planning signals in environments where past-due orders are handled manually.

Answer

Set the Positive days to 0.

Answer

Set the Coverage period to 0.

Answer

Enable the 'Include past receipts' checkbox.

Question 2

Refer to the exhibit. A production item assigned to coverage group WH1 has a requirement date of March 1st. Today is March 5th. Based on the JSON configuration, how will Master Planning treat this requirement?

Accepted Answer

A new planned order will be generated to cover the requirement.. Since the negative days value is set to 2, the system allows a delay of two days to satisfy a requirement. Because the requirement is four days late (March 1st to March 5th), it falls outside the negative days window. Consequently, the planning engine will trigger an immediate planned order to satisfy this requirement rather than attempting to satisfy it with existing supply or receipts.

Answer

The requirement will be satisfied by existing supply within the 2-day window.

Answer

The requirement will be marked as invalid and ignored by Master Planning.

Answer

The system will extend the negative days to 4 to accommodate the date.

Question 3

You are implementing Intercompany Master Planning. You need to ensure that demand from a downstream sales order in Company A triggers a planned purchase order in Company B. What is the minimum configuration required?

Accepted Answer

Set up the item as an intercompany item with a defined Vendor account.. To enable intercompany supply chain synchronization, you must define the vendor on the item in the purchasing company (Company A) as an intercompany vendor linked to the supplying company (Company B). Additionally, the intercompany planning group must be correctly set up to allow the planning engine to propagate demand across legal entities during the master planning execution run.

Answer

Create an intercompany agreement and enable automatic invoice posting.

Answer

Use the Master Planning 'Copy' functionality.

Answer

Configure a Global Address Book entry for both companies.

Question 4

Which Master Planning feature allows you to see the graphical representation of the supply and demand relationship for a specific item?

Accepted Answer

Item coverage simulation.. The Net requirements form in Microsoft Dynamics 365 Supply Chain Management provides a detailed view of the supply and demand for an item. The 'Pegging' tab within this form allows users to visualize how specific demand is satisfied by specific supply, often represented via the 'Supply Chain Map' or graphical pegging visualization tools.

Answer

Planning Optimization Map.

Answer

Forecast demand overview.

Answer

Master plan comparison report.

Question 5

You are configuring Master Planning for a new manufacturing plant. Which TWO settings in the Coverage group significantly impact the performance and output of the planning run? (Select two)

Accepted Answer

Negative days.. The 'Negative days' and 'Positive days' settings are foundational to the planning engine's logic. They define the boundaries for supply fulfillment and directly influence the number of planned orders created. Incorrect configuration of these values leads to either excessive supply signals (too many orders) or planning errors where demand is not properly associated with existing supply, making them critical for performance and accuracy.

Answer

Batch order priority.

Answer

Forecast reduction key.

Answer

Default ledger account.

Question 6

Your organization uses Planning Optimization to calculate supply requirements. A planner reports that the system is not respecting a specific purchase lead time on a vendor site. Where should you check to ensure the lead time is correctly applied during the planning run?

Accepted Answer

Default order settings.. For purchased items, the lead time is primarily defined in the 'Purchase' tab of the Item coverage setup or the Default order settings. If these are not configured, the system falls back to the Trade agreements. Checking these locations ensures the planning engine uses the correct lead time when calculating the delivery date for new planned purchase orders.

Answer

Master plan parameters.

Answer

Coverage group configuration.

Answer

Forecast plan settings.

Question 7

Which THREE actions are performed by the Master Planning engine during a full regeneration run? (Select three)

Accepted Answer

Deleting existing unconfirmed planned orders.. A full regeneration in Master Planning clears all existing planned orders and recalculates requirements from scratch. This process is essential for maintaining accuracy in dynamic supply chains. It involves identifying demand, calculating net requirements, and creating new planned orders to ensure that all supply and demand are perfectly aligned according to current settings.

Answer

Automatically firming all planned orders.

Answer

Updating the General Ledger accounts.

Question 8

Refer to the exhibit. You are running a Master Plan job. Based on the configuration in the JSON, what will happen to the previously firm-planned orders in the system?

Accepted Answer

They will remain in the system untouched.. Firm-planned orders are protected from deletion during a Master Planning run. The configuration 'DeletePlannedOrders: true' only applies to generated planned orders that have not yet been firm-planned. This ensures that the planner's manual work and commitments to production or procurement are maintained, while the system retains the flexibility to regenerate the remaining planned requirements.

Answer

They will be deleted and replaced with new planned orders.

Answer

They will be moved to the Dynamic plan instead.

Answer

They will be modified to match the new calculated requirements.

Question 9

You are using the 'Min/Max' coverage code. The system is generating excessive purchase orders even when inventory is sufficient. What is the most likely cause?

Accepted Answer

The Positive days parameter is set to 0.. If the Min/Max coverage code is triggering orders despite sufficient inventory, the most likely cause is that the 'Minimum' level is set too high or the 'Maximum' level is not properly configured. Additionally, the system may be ignoring existing supply if the 'Positive days' parameter is set to zero or a very low value in the item coverage configuration.

Answer

The Coverage period is too long.

Answer

The vendor lead time is too short.

Answer

The safety stock level is set to zero.

Question 10

A company wants to ensure that Master Planning only considers demand from specific warehouse locations while ignoring inventory in transit. Which setup on the Master Plan parameters should you configure?

Accepted Answer

Configure the 'Coverage dimension group' to deselect the 'Include' checkbox for the transit location.. Master Planning allows for granular control over inventory inclusion via the Inventory dimension groups and Plan coverage settings. By configuring the Coverage group to filter specific dimensions, planners isolate demand signals from noise caused by inventory in transit. This ensures that the generated planned orders reflect realistic supply chain availability, preventing over-ordering or redundant purchase suggestions in complex logistics environments where in-transit status misleads standard planning logic.

Answer

Enable the 'Include inventory' checkbox on the master plan to filter by transit status.

Answer

Set the 'Coverage group' to exclude the 'In transit' warehouse dimension.

Answer

Modify the 'Plan parameters' to set the 'Safety margin' to zero for all transit warehouses.

Question 11

Refer to the exhibit. The Master Planning run is failing to generate replenishment for a specific item despite a negative inventory balance. Based on the JSON configuration, what is the primary cause?

Accepted Answer

The NegativeDays value is too low to encompass the requirement.. The negative days parameter is set to 2, while the requirement gap is likely larger or the inventory is not properly linked to the demand. In Dynamics 365, negative days control how far the system looks into the future to find supply for a deficit. If the demand occurs outside the 2-day window defined, the system ignores the requirement, leading to the 'MissingDemand' error state in the planning calculation.

Answer

The PositiveDays value is too high for the item.

Answer

The CoverageGroup is set to Manual.

Answer

The StaticPlan is not configured for calculation.

Question 12

A manufacturer needs to calculate production capacity requirements during Master Planning. Which setup is mandatory to ensure capacity is considered?

Accepted Answer

Enable the 'Finite capacity' option in the Master plan parameters.. To include capacity constraints in Master Planning, you must enable resource scheduling and define appropriate time fences. Without these, the system performs infinite scheduling, assuming unlimited capacity, which leads to unrealistic production plans. Enabling capacity planning ensures the system respects the constraints of machine and human resources, providing a schedule that is actually executable within the constraints of the shop floor.

Answer

Assign a 'Resource group' to each item in the product catalog.

Answer

Set the 'Planning time fence' to zero.

Answer

Configure the 'Warehouse management' parameters for production.

Question 13

Which THREE actions are required to perform a successful Master Planning run that includes production scheduling? (Choose three)

Accepted Answer

Define resource calendars.. Successful production scheduling requires a cohesive setup of calendars, routes, and operational parameters. Without these, the system cannot calculate realistic lead times or capacity constraints. These three elements are fundamental to the Master Planning engine's ability to explode a Bill of Materials into actionable, time-phased production orders, ensuring that materials arrive when needed and production starts at the earliest possible moment without creating bottlenecks in the shop floor environment.

Answer

Configure vendor lead times.

Answer

Set up warehouse zones.

Question 14

Refer to the exhibit. Why is the system suggesting a new purchase order instead of using the existing arriving purchase order?

Accepted Answer

The NegativeDays setting of zero prevents the system from using future supply.. With 'Negative Days' set to 0, the system does not allow for a time delay between demand and supply. Any requirement must be covered by supply that is exactly on or after the requirement date. Because the existing supply arrives in 10 days, it is too late to cover current demand, forcing the system to suggest a new, immediate purchase order to meet the requirement on time.

Answer

The coverage code is set to 'Requirement'.

Answer

The static plan does not allow for Purchase Order consumption.

Answer

The item is not configured for automatic firming.

Question 15

A manufacturer uses Master Planning in Dynamics 365 Supply Chain Management. A critical finished good experiences frequent demand spikes, but procurement lead times from the primary supplier are volatile. You need to configure coverage settings to hold a specific quantity of inventory reserved exclusively for unpredictable surge demand without altering the standard safety stock calculation. Which coverage code should you implement?

Accepted Answer

Safety stock. Period coverage groups demand into fixed time buckets, which does not isolate inventory for surge demand. Requirement calculates direct one-to-one pegging. Minimum/maximum controls inventory levels based on thresholds but does not segregate stock for exclusive surge use. Safety stock is the standard mechanism to buffer against demand uncertainty and lead time variability, ensuring specific quantities are reserved to handle unexpected spikes without corrupting routine replenishment logic.

Answer

Period

Answer

Requirement

Answer

Min/max

Question 16

An organization runs Master Planning in Dynamics 365 Supply Chain Management and notices that processing times for the master schedule have increased significantly over the past quarter. You are tasked with optimizing the master planning performance. Which TWO actions should you perform? Each correct selection represents part of the solution.

Accepted Answer

Enable and configure parallel processing within the Master planning parameters.. Enabling parallel processing distributes master planning tasks across multiple threads and batch servers, drastically reducing total execution time. Activating plan versioning is unnecessary for performance optimization. Adjusting the number of tasks in the master planning parameters directly controls multithreading efficiency. Filtering items via coverage groups reduces scope but does not optimize core engine throughput compared to parallelization settings.

Answer

Activate plan versioning to archive historical master plans automatically.

Answer

Change the default coverage code on all item coverage records to Requirement.

Answer

Disable the action message generation on all active coverage groups.

Question 17

You are configuring master planning for a high-value assembly component in Dynamics 365 Supply Chain Management. The component has a strict lead time of 15 days. Management wants to ensure that planned orders are only generated if the net requirements fall outside of a specific forward time fence, while older requirements within the time fence are suppressed to avoid unnecessary procurement churn. Which master scheduling parameter should you adjust?

Accepted Answer

Coverage time fence. The coverage time fence dictates how far into the future requirements are calculated during master planning. The freezing time fence prevents planned orders from being automatically changed or deleted within the specified period. The explosion time fence controls bill of materials expansion. The capacity time fence restricts scheduling of operations. Adjusting the coverage time fence limits the planning horizon for calculating net requirements.

Answer

Freezing time fence

Answer

Explosion time fence

Answer

Capacity time fence

Question 18

A manufacturer runs master planning in Dynamics 365 Supply Chain Management using a Net requirements approach. A sales order demand exists for a finished good, and a corresponding planned production order is generated. Before firming the planned order, a user creates an urgent manual purchase requisition for the exact same component material. When master planning is run again, the system generates an additional planned production order instead of recognizing the existing purchase requisition. What is the root cause of this behavior?

Accepted Answer

Purchase requisitions are unapproved documents and are excluded from master planning supply calculations until converted to purchase orders.. Master planning evaluates supply and demand based on item coverage settings, default order types, and pegging rules. If purchase requisitions are not included in the master plan parameters as an accepted supply source, or if the item's default order type is production, the engine does not peg the requisition against the requirement. Requisitions must be formally approved and converted to purchase orders or explicitly included in inclusion parameters to be recognized by the planning engine.

Answer

The negative days parameter on the item coverage group was set to zero, preventing cross-period pegging.

Answer

The item coverage code was set to Requirement, which forces a new planned order for every single demand transaction.

Answer

The master planning timeout parameter cancelled the processing of purchase requisition supply transactions.

Question 19

You are configuring Planning Optimization for a distribution company in Dynamics 365 Supply Chain Management. A planner reports that planned purchase orders for an item are being generated even though sufficient on-hand inventory exists at the warehouse. You discover the item's coverage code is set to 'Min/Max' with a minimum of 100 and a maximum of 500, and the current on-hand quantity is 350. You need to ensure the plan does not create unnecessary replenishment while still respecting the Min/Max coverage logic. What should you do?

Accepted Answer

Verify that the item's coverage code is correctly assigned and that no negative inventory or safety stock is causing the replenishment.. The Min/Max coverage code replenishes inventory up to the maximum when projected stock falls below the minimum. In this scenario, on-hand is 350, which is above the minimum of 100, so no planned order should be generated. The unnecessary purchase orders likely stem from a misconfiguration such as incorrect coverage assignment, safety stock, or negative inventory. Verifying these factors ensures the plan respects the Min/Max logic without altering the coverage strategy.

Answer

Set the 'Minimum' value to 350 and the 'Maximum' value to 350.

Answer

Change the coverage code to 'Period' and set the coverage period to 1 day.

Answer

Disable the 'Min/Max' coverage code and use 'Requirement' instead.

Question 20

You are configuring Master Planning for a company that uses process manufacturing. Several items are produced in batch orders with co-products and by-products. The master plan must accurately plan for these items, including the co-products that are generated. Which two setup steps are required to ensure that co-products are considered during Master Planning? (Choose two.)

Accepted Answer

Assign a coverage group to the co-product item that includes the warehouse where it will be produced.. To plan co-products in process manufacturing, the formula must designate the co-product line as a co-product and link it to the correct item. Additionally, the co-product item must have a coverage group that includes the production warehouse so that Master Planning can net the co-product supply against demand. These two steps ensure that co-products are considered as supply during planning.

Answer

In the item's default order settings, set the 'Production' order type to 'Formula' and enable 'Plan co-products'.

Answer

On the formula, set the co-product's 'Burden category' to 'Co-product' and specify the planned quantity.

Answer

On the formula, specify the co-product with a negative quantity and link it to the co-product item.
