MB-310 Implement Financial Management Practice Question
A controller is reviewing a vendor invoice that was posted with an incorrect expense amount. The invoice is already posted and the accounting period is still open. The controller needs to correct the expense account and amount while preserving a clear audit trail, and the vendor balance must also be adjusted. Which action should the controller take?
⚠ Common exam trap
The trap here is thinking a general journal adjustment fixes a vendor invoice, when it only moves ledger amounts and leaves the vendor subledger balance wrong.
Answer choices
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
✓
Reverse the posted vendor invoice and then enter a new vendor invoice with the corrected expense amount and account.
The supported correction for a posted vendor invoice is to reverse it and then enter a corrected invoice. Reversal creates offsetting ledger and subledger entries, so the vendor balance is restored, and the new invoice records the correct expense account and amount. Both documents remain in the system, providing the audit trail the controller needs. Direct edits or deletions of posted transactions are not allowed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Post a general journal entry to move the amount between the expense accounts and leave the vendor balance unchanged.
Why it's wrong here
A general journal can move amounts between ledger accounts, but it does not touch the vendor subledger balance because it has no vendor transaction. The invoice amount owed to the vendor would remain overstated or understated, so the vendor balance would not be adjusted and the correction would be incomplete.
- ✗
Delete the posted vendor invoice and re-enter it with the correct information.
Why it's wrong here
Posted vendor invoices cannot be deleted. Deleting posted transactions would destroy the audit trail and is not supported in the application. The only supported way to neutralize a posted invoice is to reverse it, which leaves both the original and the reversal in the ledger for traceability.
- ✗
Edit the posted vendor invoice journal and change the expense amount and main account directly.
Why it's wrong here
Posted vouchers in Dynamics 365 Finance cannot be edited directly. The ledger and subledger entries are already recorded and the system locks posted transactions from modification to protect audit integrity. Attempting to edit a posted invoice journal is not possible through the user interface, so this approach cannot correct the expense or the vendor balance.
- ✓
Reverse the posted vendor invoice and then enter a new vendor invoice with the corrected expense amount and account.
Why this is correct
Reversing the posted vendor invoice creates a reversing entry that offsets the original accounting and vendor balance, and then a corrected invoice records the right expense. This preserves a full audit trail because both the original and reversal remain visible, and the vendor balance reflects the corrected amount. It is the standard supported correction method for posted vendor invoices.
