Microsoft Dynamics 365 Business Central Functional Consultant MB-800 Exam Questions with Experts Answers Updated Recently

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

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.

Buying groups require all invoices in a month to be due on the 20th of the following month (from the case study).

In BC, this is achieved by setting up Payment Terms = CM+20D (Current Month + 20 Days). Example: Invoice on Sept 5 → due Oct 20.

Payment terms are assigned directly to the customer card, not to the posting group or price group.

Option E (D20) would set due date 20 days after invoice date, which is incorrect.

Assigning to Customer Posting Group or Price Group does not control due dates.

Correct: A and C

Comprehensive Detailed Explanation

The requirement: “You need to train users on how to process a special order for an established customer.”

From the case study:

“Special orders from new customers have a 25% prepayment. Established customers have only a 15% prepayment.”

Prepayments must be invoiced before the final invoice is posted.

Step-by-step process in Business Central:

Create a sales order

The user begins by creating a sales order for the special order.

Enter 15% in the Prepayment % field

Since this is for an established customer, the prepayment percentage is 15%.

The Prepayment % field on the sales order line or header controls how much must be prepaid before the order can be processed.

Enter the code for due on receipt in the prepayment payment terms code

Prepayments are typically due immediately. The code for “due on receipt” ensures that the prepayment invoice requires immediate payment.

Post and print the prepayment invoice

This generates the prepayment invoice for the customer and ensures that prepayment is received before delivery.

Why not “Enter the code for net 30 in the prepayment payment terms code”?

That applies to wholesale customer regular payment terms, not to prepayments. Prepayments are due immediately.

Why not 25%?

25% prepayment applies to new customers. For established customers, the requirement specifies 15%.
