Comprehensive Detailed Explanation

Set up a new fiscal year

In Business Central, fiscal years are created in the Accounting Periods page.

To start a new fiscal year, you must Select Create Year, which generates the periods for the new fiscal year.

Other options like Close Year or Fiscal Year Balance are for closing or balancing, not for initial setup.Correct: Select Create Year

Define the fiscal year start date

The case study specifies that the company’s fiscal year starts on June 1.

Therefore, when creating the new fiscal year, you must ensure the first period begins on June 1.

The correct action is Check New Fiscal Year for June 1.Correct: Check New Fiscal Year for June 1

Restrict posting

The business requirement is:

Restrict users to post only in the current month.

Only certain accounting users may have broader posting permissions.

In General Ledger Setup, the Allow Posting From and Allow Posting To fields control the global posting date range.

For user-specific restrictions or exceptions, User Setup allows overriding posting ranges for individual users.

Since the requirement is to restrict all users generally, the best action is:In General Ledger Setup, set the Allow Posting From and Allow Posting To options to current dates.Correct: In General Ledger Setup, set the Allow Posting From and Allow Posting To options to current dates

User Setup and Posting Date Permissions

Requirement: Each salesperson must be assigned to only one region, and combinations must be enforced automatically to avoid inconsistent commission reporting.

In Business Central, this is achieved by defining a Dimension Combination rule between the Salesperson dimension and the Region dimension.

Setting it to Blocked prevents users from posting with an invalid salesperson-region combination.

Other options:

A. Limited restricts only dimension values on certain accounts.

B. Default Dimension Priorities controls which default dimension wins, but does not enforce uniqueness.

D. Default Dimensions on Customer Cards helps with defaults, but doesn’t prevent invalid combos.

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 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

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 requirement is:

“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.”

In Business Central, the General Ledger Entries page can display amounts in two different ways:

Amount (positive/negative): This is the default display of entry amounts as signed numbers.

Debit Amount / Credit Amount (separate fields): This allows accounting teams to clearly see whether an entry is a debit or a credit, consistent with traditional accounting presentation.

The configuration option "Debit/Credit" is specifically provided to control this display. By enabling this setting, amounts are shown in two columns (Debit Amount and Credit Amount) instead of one column with positive/negative signs.

Why not the other options?

B. Show Amounts – This relates to toggling whether amounts are displayed on certain ledger pages but does not change the format to Debit/Credit.

C. Check G/L Account Usage – This is a validation function for checking how accounts are used, not related to entry display format.

D. G/L Account Card – Used to configure properties of individual G/L accounts (posting type, direct posting, account category), not the general display mode for entries.

Therefore, the correct configuration to meet the requirement is Debit/Credit.

The requirement is: “Customer pricing is determined by the customer market type (Retail, Veterinarian, Breeder). Each customer is associated with only one market type.”

A. Assign the Customer Price Group code on the customer card → Correct, because each customer must be tied to its market type via a Customer Price Group.

C. Create a Sales Price List by using the assign-to type of Customer Price Group → Correct, because pricing and discounts should be managed at the group level, not per individual customer, ensuring easier maintenance.

E. Create Customer Price Groups that allow line discounts → Correct, because discounts are offered by item, brand, or product category, and must flow to sales lines automatically.

Incorrect options:

B. Exclude line discounts → Opposite of requirements.

D. Create a Sales Price List for the customer → Not scalable; must be done by group, not individual customer.

Correct answers: A, C, E

The scenario requires configuring Business Central to meet sales department needs:

Sales discounts

Requirement: “Discounts must post to a unique general ledger (G/L) account.”

In Business Central, this is managed through the Discount Posting field in Sales & Receivables Setup.

When enabled, the system posts line discounts and invoice discounts to dedicated G/L accounts instead of combining them with revenue.

This ensures transparency and compliance with accounting’s requirement to track discounts separately.

Correct match: Sales discounts → Discount posting

Credit limits

Requirement: “The sales department should receive a warning when entering the order if a customer is over their credit limit.”

In Business Central, this behavior is controlled by Credit Warnings in the Sales & Receivables Setup.

This setup defines whether to warn the user, block posting, or allow posting when the customer’s balance exceeds the defined credit limit.

Correct match: Credit limits → Credit warnings

Why not the other options?

Calc. inv. discount – Controls whether invoice discounts are automatically calculated, but not relevant here.

Stockout warnings – Alerts when an item has insufficient inventory; unrelated to discounts or credit limits.

The requirement is: “You need to configure retail store customer cards to track revenue by market.”

In Business Central, to track revenue by customer market (Retail, Veterinarian, Breeder), you configure default dimensions on the Customer Card.

Assign the dimension code → Market

The business wants to analyze revenue by Market (Retail, Veterinarian, Breeder).

Therefore, the dimension code must be Market.

Assign the dimension value code → Retail

For this specific setup, the customer is a retail store, so the dimension value must be Retail.

Select a value posting → Same code

To ensure that every posting for this customer always carries the same dimension value, use Same Code.

Other options:

Blank = no default dimension.

No code = optional dimension.

Code mandatory = requires entry but allows flexibility in values.

Since we want strict tracking by a fixed market (Retail), Same code is correct.

This ensures that every transaction posted for the customer will always have Market = Retail, enabling accurate revenue tracking.
