When a cash receipt is applied incorrectly, you cannot simply delete or reverse it — instead, you must unapply the entries.

Steps:

From the relevant Customer Ledger Entry, select Unapply Entries.

Unapply the second payment first (because payments are applied in sequence).

Unapply the first payment (the erroneous one).

Reapply the second payment correctly to the customer ledger entry.

This way, the first erroneous cash receipt is removed, and the correct receipt remains applied.

Why not B or C?

Reverse Transaction is for reversing journal entries or posted G/L transactions, not for applied customer ledger entries.Why not D?

Posting a reversing cash receipt is unnecessary; the built-in Unapply Entries function is the proper approach.

Sales Invoice Correction

Based on the scenarios, here is the correct action for each:

Scenario 1: Use this action when the posted invoice has not been paid and the original invoice was posted from a sales order.

Action: Correct

The Correct action is specifically designed for this scenario. It automatically creates a new sales order, reverses the original posted invoice, and copies the original lines to the new order. The new sales order is then ready for editing, allowing you to make corrections and post it again.

Scenario 2: Use this action when the posted invoice has not been paid and the original invoice was not posted from a sales order.

Action: Cancel

The Cancel action is used when the invoice wasn't created from a sales order. It creates a credit memo to fully reverse the posted invoice. This effectively cancels the invoice without needing to go through a new sales order process, as no original sales order exists.

Scenario 3: Use this action when the posted invoice has been paid and warehouse documents are not required.

Action: Create corrective credit memo

The Create corrective credit memo action is the appropriate choice when the invoice has already been paid. Since the payment has been applied, you can't simply "correct" or "cancel" the invoice directly. Instead, you create a credit memo that can then be applied against the payment, effectively reversing the transaction. This action is also used when warehouse documents are not necessary, as a separate sales return order with warehouse processes is not required.

The AR users reported an issue about reconciling AR subledger to the G/L. In Business Central, subledger control accounts (like Accounts Receivable and Accounts Payable) must not be posted to directly; they should only be posted through transactions (invoices, payments).

If Direct Posting = Yes, users can post directly into AR or AP control accounts, which causes reconciliation issues.

To prevent this, you set Direct Posting = No on the G/L Account Card for control accounts.

Why not others:

A. Switch Blocked on the Customer Card → Blocks transactions but does not solve reconciliation issues.

B. Switch Direct Posting on the G/L Account Card to Yes → Makes the issue worse.

C. Switch Blocked on the G/L Account Card to Yes → Prevents all postings, even system ones, which is incorrect.

Correct answer: D. Switch Direct Posting on the G/L Account Card to No

The Accounts Receivable (AR) team often needs to correct payment applications when cash is applied incorrectly. In Business Central, unapplied entries can be corrected in several ways:

From the Customer Card, under Navigate > Ledger Entries, users can select entries and use the Unapply Entries action.

From the Customer Ledger Entries page, users can directly select a posted application and choose Unapply Entries.

The Detailed Customer Ledger Entries page is used for analysis and shows how entries were applied, but the actual “Unapply” action is not typically performed here (it is read-only in terms of correction).

“Apply entries” can be done from Detailed Customer Ledger Entries, but unapplies are performed from Customer or Customer Ledger Entries.

Correct answers: A and C
