The company distributes natural pet products in the Northwest region of the country/region. Products are purchased directly from manufacturers and distributed by using its own fleet of trucks. When the company started, deliveries were within a three-hour radius of the warehouse. Due to regional growth, current deliveries require drivers to stay overnight on some routes. The company plans to open a second warehouse to expand the region and eliminate overnights for route drivers. The company also plans to hire a second group of employees to run operations in this new location. The finance and accounting teams will remain in the original location. The company uses a third-party system for financials and order management. The finance department stated that the company’s fiscal year begins on July 1 and ends on June 30. The mm/dd/yyyy date format is used. As part of the expansion, the owner plans to upgrade to an ERP system and use Business Central to fulfill the company requirements and manage growth. Current environment - Orders - • Orders are emailed to customer service and manually keyed into the inventory system. Pricing and discounts - • Customer pricing is determined by the customer market type. Customer market types are Retail, Veterinarian, and Breeder. Each customer is associated with only one market type. • Vendors offer monthly promotions to customers by item, brand, or item category. • Invoices should show each customer’s base price, the discount amount, and the net price. Accounts payable - • The company wants to expand vendor payment options in the new system. Requirement - Customers - • The sales team must be able to do the following: o Quickly set up new customers with the proper settings based on customer type. o Identify customers by market type. Customer posting groups will be used to identify which market the customer belongs to. • Base price is determined by the customer market type. • The sales department should receive a warning when entering the order if a customer is over their credit limit. Sales - • Customer discounts are offered for specific time frames by item, brand, or product category. Discounts should be added to sales lines automatically. • Discounts must post to a unique general ledger (G/L) account. • The business needs to be able to track revenue by location, market, and product category dimensions. Locations 100 and 200 will be set as default dimensions on the two warehouse locations. Food, treats, toys, and supplies are the required product categories, which will be set as default dimensions on the item cards. Each customer card will have a default market dimension. • The sales manager wants to delete canceled orders and automatically archive them. Warehouse - • Orders will be fulfilled from two possible warehouse locations. • Product will be transferred between locations by using transfer orders. Sales invoices - • Invoices will be posted after delivery. • Invoices will be emailed to the customer. • The sales department must be able to quickly correct posted invoices for the following scenarios: o Posted invoices that have not been paid. o Posted invoices that have been paid. o Posted invoices created from sales orders. o Posted invoices not created from sales orders. Accounting - • The finance department requires that the company has 12 monthly accounting periods per fiscal year. • Finance department users must be able to reconcile the accounts receivable (AR) subledger to the G/L account at month end. • AR department users need the ability to settle and close invoices when customers take payment discounts after the payment discount date has passed. AR users should be allowed to accept or reject the payment tolerance. • Accounts payable (AP) department users must be able to pay vendors by electronic funds transfer (EFT) and use a payment journal batch named EFT to process payments. • When viewing G/L entries, the finance and accounting teams must be able to see debits and credits instead of a positive or negative amount. • The company needs to be able to track expenses by department and location. The departments are sales, operations, and administration. • AR must be able to correct cash application entries. Issues - Payment application - • Customers may have several stores that are responsible for their own orders and payments. • Occasionally, AR clerks mistakenly apply payments to the incorrect customer invoice. Invoicing - • When items are delivered, customers refuse the items for reasons such as damaged or wrong item. • After the invoices are posted, they must be corrected, which is time-consuming. Warehouse - • The sales department and warehouse managers must have visibility into products that are in the process of being transferred between locations. Accounts - • Customer accounts are difficult to view by market type. • The finance team does not have the ability to report revenue by customer type. Accounting - • AR users often find variances between the AR subledger and G/L account. • Customers often take the payment discount after the payment discount date has passed, leaving open invoices for small amounts. • The AP department is unable to pay vendors by EFT in the current system. • Finance and accounting team members have trouble validating postings when they use only the amounts field on G/L entries. • The finance department is unable to run financial reports by market. All revenue postings must reference a market. You need to train the Accounts Receivable (AR) department how to correct customer payment application issues. What are two possible ways to achieve this? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

Community Insight
The item tests which Business Central pages expose the Unapply Entries action for customer ledger entries, and the trap is assuming the Customer Card provides the same entry-level correction capability.
In Business Central, a mistaken customer payment application is corrected by unapplying the ledger entries, and this can be done from the Customer Ledger Entries page or the Detailed Customer Ledger Entries page. This page establishes answers A and B as the two complete solutions for the MB-800 case study scenario.
Selecting option C (unapply from the customer card), because the customer card looks like the central place to manage a customer — but it only shows balances and statistics, not the individual open and applied ledger entries needed to unapply a payment.

Expert Analysis
Why the Answer Is Correct
When AR clerks apply a payment to the wrong customer invoice, the application itself must be reversed, and Business Central exposes the Unapply Entries action on the Customer Ledger Entries page and on the Detailed Customer Ledger Entries page. Both pages list the applied customer ledger entries, so the clerk can select the incorrect application and unapply it, which reopens both the payment and the invoice. Once the entries are unapplied, the payment can be reapplied to the correct invoice, which is exactly the "correct cash application entries" requirement in the case study. Because the question asks for two complete solutions, A and B are both valid and each independently resolves the issue.Why the Other Options Are Wrong
Option C is incorrect because the Customer Card is not an entry-level page — it displays the customer's balance, statistics, and setup fields, but it does not expose the Unapply Entries action on the applied ledger entries. Option D is incorrect because applying entries is the operation that created the error in the first place; applying from the Detailed Customer Ledger Entries page does not reverse the existing wrong application, so it cannot correct the mistake. Only the unapply action reverses an existing application and frees the payment and invoice to be matched again. This is why the two acceptable answers must both begin with "Unapply entries."Community Comment Notes
Community sentiment strongly supports A and B, with Lavoisier stating that "C is wrong because you can't unapply entries directly from the customer card" and linking the Microsoft Learn article on applying sales transactions manually. zigzag01 reported testing the scenario in Business Central and concluding that "the only two ways are" unapplying from the detailed customer ledger entries and unapplying from the customer ledger entries. ivanrlg also settled on AB, and the vote tally of 75 for AB versus 25 for BC reflects that consensus. One commenter, 3e11d6a, argued for BC using the same Microsoft article, but the article's own procedure confirms that unapplying happens on ledger entry pages rather than on the customer card.Exam Takeaways
The MB-800 case study frames this as training the AR department, so the exam expects you to know the exact navigation path rather than just the concept of unapplying. Remember that corrections always start by reversing the entry-level application, then reapplying to the correct open invoice.Official Reference
Exam Strategy
In case-study sections, read the requirement wording literally: "correct customer payment application" means reversing an existing application, so eliminate any option whose verb is "Apply." Then confirm the page supports entry-level actions — Customer Ledger Entries and Detailed Customer Ledger Entries do, while the Customer Card does not.
Frequently Asked Questions
Why can't I unapply entries from the customer card in Business Central?
The Customer Card only shows balance, statistics, and setup fields, not the individual applied ledger entries. The Unapply Entries action is available on the Customer Ledger Entries and Detailed Customer Ledger Entries pages.
Why is option D, Apply entries from the Detailed Customer Ledger Entries page, not a valid fix?
Applying entries is the action that caused the wrong match. Correction requires reversing the existing application with Unapply Entries first, then applying the payment to the correct invoice.
