MB-310 Practice Question: Implement and Manage Accounts Payable and Expenses
A Dynamics 365 Finance accounts payable manager needs to configure the system so that vendor invoices entered in the pending vendor invoice form can be posted only after a three-way matching check against the purchase order and product receipt. The matching must block posting when the net unit price variance exceeds 5 percent. What should the manager configure first?
⚠ Common exam trap
The trap here is assuming that a vendor posting profile or an approval workflow can enforce invoice matching tolerances, when only an invoice matching policy controls three-way matching and price variance blocking.

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
✓
Set up an invoice matching policy with a three-way matching requirement and assign a price tolerance of 5 percent.
Three-way matching and price tolerances are both defined inside an invoice matching policy. The policy is attached to a vendor or item and determines whether the system requires purchase order, product receipt, and invoice alignment. Setting a 5 percent price tolerance within that policy causes the system to hold or block posting when the calculated variance exceeds the limit, which is exactly what the manager needs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a procurement category hierarchy and assign it to the vendor record.
Why it's wrong here
Procurement category hierarchies are used to classify spend and drive purchasing policies, not invoice matching. Assigning a category to the vendor does not create matching requirements or tolerances, so it cannot prevent posting when the net unit price variance exceeds the configured threshold.
- ✗
Create a vendor posting profile that requires approval before posting pending vendor invoices.
Why it's wrong here
A vendor posting profile controls which summary accounts are used for vendor transactions; it does not enforce purchase order matching or price tolerances. Approval workflows can route invoices for review, but they do not perform the automated three-way comparison against the product receipt and purchase order, so posting would not be blocked by a price variance.
- ✗
Enable the Invoice register journal and set the journal name to require approval before transfer.
Why it's wrong here
The invoice register journal is used to record invoices before they are transferred to the pending vendor invoice form. Requiring approval on the journal controls who can transfer records, but it does not compare invoice lines to purchase order lines or product receipts and therefore cannot enforce the 5 percent price tolerance.
- ✓
Set up an invoice matching policy with a three-way matching requirement and assign a price tolerance of 5 percent.
Why this is correct
Invoice matching policies define whether two-way, three-way, or charge matching is required, and the associated tolerances control when posting is blocked. Configuring the policy with three-way matching and a 5 percent price tolerance makes the system compare the invoice, purchase order, and product receipt before allowing posting, which directly satisfies the requirement.
