Create Purchase Order from Work Order for Out-of-Stock Parts
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?
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.
⚠ Common exam trap
Many candidates 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.

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?
easy- A.Create a work order and update the status to 'In Progress'.
- B.Use Resource Scheduling Optimization to assign the technician.
- ✓ C.Reserve the part from the warehouse using the inventory transfer functionality.
- D.Create a purchase order for the part and mark the work order as requiring approval.
Why C: The inventory management capabilities in Dynamics 365 Field Service allow you to reserve parts from the warehouse using the inventory transfer functionality, ensuring the part is available before the technician arrives. Option A is incorrect because updating the work order status to 'In Progress' does not affect inventory availability. Option B is incorrect because Resource Scheduling Optimization assigns technicians but does not manage inventory. Option D is incorrect because creating a purchase order is for ordering new stock, not for reserving existing inventory.
