Question 520
After resolving this Dynamics 365 Finance case: A finance analyst changes today's market rate but a previously posted voucher is expected to automatically recalculate historical accounting values. What preventive control belongs in the operating procedure?
Explanation
Correct Answer
Keep a versioned rate approval and period-specific revaluation procedure. This prevents recurrence of the identified mechanism: Changing an exchange-rate table does not retroactively change every posted ledger transaction. Validate the control by checking: The historical voucher remains traceable and authorized revaluation or adjustment entries reconcile separately.
Incorrect Answers
Test finance journal controls against representative roles when closing periods. That safeguard is aimed at a different risk: A financial posting date falls in an open fiscal year but the user's module period is restricted. It does not most directly prevent recurrence of: Changing an exchange-rate table does not retroactively change every posted ledger transaction.
Verify rate type, date and currency pair before finance period revaluations. That safeguard is aimed at a different risk: A foreign-currency receivable revaluation is incorrect because an obsolete exchange rate type is used at month-end. It does not most directly prevent recurrence of: Changing an exchange-rate table does not retroactively change every posted ledger transaction.
Reconcile accounting entries for both gain and loss test cases. That safeguard is aimed at a different risk: The year-end currency conversion leaves a residual balance in the wrong gain/loss account. It does not most directly prevent recurrence of: Changing an exchange-rate table does not retroactively change every posted ledger transaction.
