The answer is incorrect inventory posting profiles, as this is the most likely cause when a purchase invoice fails to update the general ledger in Dynamics 365 Finance. Inventory posting profiles are the technical backbone that maps inventory transactions—like purchase invoices—to specific general ledger accounts; if these profiles are misconfigured or missing, the system cannot determine where to post the debit or credit entries, leading to a failed or incorrect update. On the MB-920 exam, this tests your understanding of core financial posting mechanics, often appearing as a scenario where intermittent failures occur despite other settings being correct—a common trap is confusing this with budget control or payment schedules, which affect different stages of the transaction lifecycle. Remember the mnemonic: “Profiles post, budgets block, schedules schedule, audits review” to keep each function distinct.

Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Inventory posting profiles define how inventory transactions are posted to the general ledger. Misconfiguration can cause intermittent failures when posting invoices that involve inventory.
B
Improperly configured audit policies
Why wrong: Audit policies are used to review transactions after posting for compliance, not to affect the posting process itself.
C
Budget control settings are too restrictive
Why wrong: Budget control prevents posting when budget is exceeded, but the issue is intermittent and not related to budget availability.
D
Incorrect payment schedule setup
Why wrong: Payment schedules determine due dates for payments, not general ledger posting behavior.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Incorrect inventory posting profiles
Option A is correct because inventory posting profiles determine how inventory transactions are posted to the general ledger. If they are not correctly set up, posting may fail or update the wrong accounts. Option B is wrong because payment schedules affect payment timing, not general ledger updates. Option C is wrong because audit policies review transactions after posting, not during. Option D is wrong because budget control settings prevent posting when budget is exceeded, but the issue is intermittent and not related to budget.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
