Implement Master Planning
This domain covers configuring and running Master Planning in Dynamics 365 Supply Chain Management: coverage codes, coverage groups, master plan setup, forecast integration, planned order firming, and interpreting planned order output. Questions present operational symptoms (no planned orders, wrong quantities, stale plans) and ask which configuration or form resolves them.

What this domain covers
What to know about Implement Master Planning
Be able to configure coverage codes and coverage groups, set up a master plan with forecast integration, and run planning to generate planned orders. The single most important thing: know which setting on the item or plan controls whether and how replenishment is suggested.
Configuring coverage codes (Min/Max, Period, Requirement) and coverage groups on released products
Setting up master plans, including forecast plans and demand forecast reduction keys
Firming planned orders manually or automatically via the master plan's firming settings
Running master planning and reading planned order output, action messages, and delays
Watch out for
Common Implement Master Planning exam traps
- ▸Confusing coverage group settings with item coverage settings, so overrides on the released product are missed
- ▸Forgetting that a demand forecast only affects planning when a forecast plan is linked and reduction keys are set
- ▸Assuming Master Planning creates orders when the item's default order type, minimum, or lead time blocks replenishment

A company uses Master Planning with a plan that has 'Firming' enabled. The planner wants to automatically firm planned purchase orders that are within a 10-day time fence from today. The plan is set up with a firming time fence of 10 days. After a master plan run, the planner notices that some planned purchase orders within the 10-day window were not automatically firmed. What is the most likely cause?
Hard2You are a functional consultant configuring Master Planning for a company that manufactures bicycles. The company has a policy that certain critical components, such as frames, must be produced in-house and never purchased. You need to ensure that Master Planning generates planned production orders for these components, but you also want the system to suggest purchasing raw materials like aluminum tubing. Which configuration should you set on the item's default order type?
Medium3A company is running master planning in Dynamics 365 Supply Chain Management. They want to simulate the effect of a new master plan without affecting existing planned orders. Which type of master plan should they create?
Easy4A 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?
Hard5You need to ensure that planned purchase orders are automatically firmed if they fall within a 5-day window from today. Which form should you use to automate this process?
Easy6A company uses Dynamics 365 Supply Chain Management. They have a master plan that includes a demand forecast. The forecast is reduced by actual sales orders. A sales order for 150 units is confirmed against a forecast of 200 units for the same period. What is the resulting forecast consumption, and how does it affect planned orders?
Hard7You notice that planned orders are being created with very small quantities, resulting in excessive production setups. Which coverage setting should you adjust to consolidate these requirements?
Medium8A company uses a 'Period' coverage group. How does the planning engine determine the quantities for replenishment?
Medium9A production planner is reviewing the master plan and notices that a planned production order for a subassembly has a status of 'Unprocessed'. The planner wants to firm this planned order to a production order. What is the correct sequence of actions?
Easy10Your company uses a 'Coverage code' of 'Period' for most items. You need to understand how this code influences the generation of planned orders. What is the effect of using the Period coverage code?
Medium11Refer to the exhibit. Given the JSON settings, what happens when a sales order for 50 units is confirmed against a forecast of 200 units?
Hard12A 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?
Medium13A distribution company needs Master Planning to generate planned transfer orders that replenish a warehouse from a central distribution center. The item is currently set up with a coverage code of 'Min/Max' and a default order type of 'Purchase'. What must be configured to allow the planning run to create planned transfer orders instead of planned purchase orders?
Medium14Which plan type should you use to run a simulation without affecting the live production schedules?
Easy15A company uses Dynamics 365 Supply Chain Management. They have a master plan that is configured to use 'Forecast' as a demand type. They have a sales forecast for 100 units in January. However, they receive a firm sales order for 80 units in January. How does Master Planning handle the forecast and the sales order to avoid double-counting demand?
Medium16A manufacturing company runs Master Planning nightly. The production planner reports that for several finished goods, the system plans production orders for components that already have sufficient on-hand inventory at the same warehouse. The components have a coverage code of Requirement and a positive on-hand quantity, but the master plan still creates planned purchase orders for them. You need to determine the most likely cause. What should you check first?
Medium17You 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?
Medium18Which status must a planned order reach before it can be processed into a production or purchase order?
Easy19You are debugging a Master Planning run and notice that certain production components are not being planned correctly. Which THREE areas should you inspect? (Select three)
Hard20A supply chain manager needs to run Master Planning for a specific item and wants the planning engine to consider only the demand and supply for that item, ignoring all other items. Which action should the manager take when starting the planning run?
Easy21You are setting up a Master Plan for a seasonal product. You need to ensure that the plan considers a specific demand forecast that is higher than current sales trends. Which configuration is required?
Medium22You notice that Master Planning is not suggesting purchase orders for an item even though the stock is below the minimum. What is the most likely reason?
Medium23A supply chain manager needs to run Master Planning to generate planned orders for a specific set of items. They want to limit the planning run to only those items, ignoring all others. Which parameter in the Master Planning run dialog should they use?
Easy24You are configuring safety margins in Dynamics 365 Supply Chain Management to protect against demand variability. Which TWO settings can be used to add a buffer to planned orders? (Choose two.)
Hard25Which TWO factors influence the replenishment calculation for an item using the 'Min/Max' coverage code? (Choose two)
