Troubleshoot General Ledger vs Subledger Mismatch in Accounts Payable
A manufacturing company uses Dynamics 365 Finance. The finance team notices that the general ledger balances do not match the subledger details for accounts payable. What should you troubleshoot first?
Quick Answer
The answer is to run the 'Troubleshoot GL balance' report in Accounts payable. This report is specifically designed to identify discrepancies between the general ledger and subledger in accounts payable by comparing the detailed vendor transactions against the aggregated ledger balances, pinpointing where a general ledger subledger mismatch occurs. On the Microsoft Dynamics 365 Fundamentals ERP MB-920 exam, this question tests your understanding of core financial reconciliation processes and common troubleshooting steps in Dynamics 365 Finance. A frequent trap is confusing this report with settlement or payment tools—remember that settlement handles vendor payments, invoice approval workflows manage authorization, and the payment journal report only shows payment lines, none of which address balance mismatches. For a quick memory tip: when the GL and subledger don't match, think "Troubleshoot first, settle later."

Correct answer & explanation
✓
Run the 'Troubleshoot GL balance' report in Accounts payable.
The correct first step is to run the 'Troubleshoot GL balance' report in Accounts payable. This report is specifically designed to identify discrepancies between the general ledger and the subledger for accounts payable. Option A is incorrect because the invoice approval workflow affects approval processes, not GL-subledger balances. Option B is incorrect because reviewing the vendor payment settlement process pertains to payments, not balance discrepancies. Option D is incorrect because re-running the payment journal report shows payment details, not balance reconciliation.

Same concept, more angles
2 more ways this is tested on MB-920
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. A company uses Dynamics 365 Finance. The finance team notices that the general ledger balances do not match the subsidiary ledger balances for accounts payable. What should they investigate first?
hard- A.The audit trail of posted transactions
- ✓ B.Unposted vendor invoices and payments
- C.The process automation framework
- D.The posting profiles for vendors
Why B: The most common cause of a mismatch between the general ledger and the accounts payable subsidiary ledger is unposted vendor invoices or payments that are still in draft or pending posting. Therefore, the finance team should first investigate unposted vendor invoices and payments (Option B). Option A (audit trail of posted transactions) would only show transactions that have already been posted, not those waiting to be posted, so it would not help identify the cause. Option C (process automation framework) is unrelated to ledger reconciliation. Option D (posting profiles for vendors) define how transactions post to the general ledger but do not directly address the mismatch.
Variation 2. A company uses Dynamics 365 Finance. The finance team notices that the general ledger journal balance does not equal the sum of debits and credits. What could cause this discrepancy?
medium- A.Incorrect voucher number series
- B.Incorrect posting profile configuration
- ✓ C.Unbalanced journal entry
- D.User permissions
Why C: An unbalanced journal entry, where total debits do not equal total credits, will cause the general ledger balance to not match the sum of debits and credits. Option A is incorrect because the voucher number series merely assigns identifiers and does not affect accounting balances. Option B is incorrect because posting profile configuration determines how transactions are posted to accounts but does not cause an imbalance if the journal entry itself is balanced. Option D is incorrect because user permissions control access rights, not the balancing of journal entries.
