Quick Answer
The correct answer is to create a purchase order from the work order to procure the part. This is the right choice because Dynamics 365 Field Service integrates inventory and work order management, allowing a scheduler to generate a purchase order directly from the work order when a part is out of stock, which triggers procurement and ensures the item arrives before a technician is dispatched. On the MB-910 exam, this scenario tests your understanding of Field Service’s inventory workflows and the distinction between creating a purchase order versus simply reserving stock or rescheduling the job—a common trap is assuming the scheduler must manually order parts outside the system. To remember this, think “PO from WO”: when a part is out of stock, the purchase order flows directly from the work order to keep service on track.
This MB-910 practice question tests your understanding of describe dynamics 365 field service. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A work order requires a specific part that is currently out of stock in the warehouse. What should the scheduler do to ensure the part is available before assigning a technician?
Change the work order type to 'Service'
Why wrong: Work order type does not affect inventory.
Create a purchase order from the work order to procure the part
Purchase orders can be created to order needed parts.
Run Resource Scheduling Optimization
Why wrong: RSO schedules resources, not procurement.
Close the work order and reopen it later
Why wrong: Closing does not resolve the inventory issue.

Correct answer & explanation
Create a purchase order from the work order to procure the part
Option B is correct because Dynamics 365 Field Service allows schedulers to create a purchase order directly from a work order when a required part is out of stock. This ensures the part is procured and available before a technician is assigned, preventing delays and incomplete service calls.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Close the work order and reopen it later
Why it's wrong here
Closing does not resolve the inventory issue.
Common exam traps
The trap here is that candidates may confuse Resource Scheduling Optimization (RSO) with inventory management, assuming it can handle part shortages, when in fact RSO only optimizes technician scheduling and does not interact with procurement or stock levels.
Detailed technical explanation
In Dynamics 365 Field Service, the 'Create Purchase Order' action on a work order generates a purchase order linked to the work order's service account and line items. This integration ensures that once the purchase order is fulfilled, the inventory is updated and the work order can proceed with the correct part allocation. A real-world scenario is when a technician needs a specialized component that is not stocked locally; the scheduler can create a purchase order to a vendor, and the system tracks the order status until the part arrives.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your organization needs to schedule a technician to repair a machine at a customer site. The repair requires a specific part that is currently out of stock. What should you do to ensure the part is available before the technician arrives?
easyWhy C: Option B is correct because the inventory management capabilities in Field Service allow reservations and transfers to ensure parts are available. Option A is wrong because manually updating the work order does not affect inventory. Option C is wrong because the Resource Scheduling Optimization (RSO) schedules technicians but does not manage inventory. Option D is wrong because purchase orders are for ordering, not for reserving existing stock.
