Microsoft Updated MB-800 Exam Questions and Answers by leilani

The scenario describes cash and carry sales, where customers pay immediately at the desk and sales invoices must be posted as paid in full at the time of sale. In Dynamics 365 Business Central, this is achieved by setting Payment Terms that indicate no delay between invoice date and due date.

Why D (Payment Terms = 0D)

The Payment Terms setup in Business Central allows you to define how the Due Date is calculated.

For cash and carry transactions, the invoice is due on the same day (zero days). Setting the Due Date Calculation to 0D ensures that the system always marks invoices as immediately due, reflecting the cash-and-carry business process.

This aligns with requirements: “Invoices must be posted at the cash and carry desk at the time of sale” and “Invoices already paid in full should not appear as outstanding on aging reports.”

Why not A (Payment Service)

Payment Services are used for integration with external services like PayPal or credit card gateways. Wide World Importers does not require a POS or online payment gateway—just simple cash handling at the desk.

Why not B (Direct Debit Mandate)

Direct Debit is used for recurring bank withdrawals (SEPA mandates, subscription-type payments). It does not apply to one-time, immediate cash payments.

Why not C (Payment Method = Bank Account)

While Payment Methods (e.g., Cash, Bank Transfer, Check) are also important for tracking how customers pay, the critical requirement in the scenario is ensuring the invoice is due immediately. That is achieved by Payment Terms = 0D, not by Payment Method alone.

Best Practice Setup in Business Central for Cash & Carry:

Payment Terms: 0D (ensures invoice due immediately).

Payment Method: Cash (ensures posted directly against the cash account).

Apply to invoices at posting: Invoices will automatically be shown as paid in full.

This combination ensures correct cash sales processing and eliminates the issue noted in the case study where invoices incorrectly appear in aging reports.

Regular price: $20.00

Buying group discount: $18.00

Autumn promotion price: $19.00

Overstock special: 15% off regular price ($20 × 0.85 = $17.00)

However, the case study requires the system to always give the lowest available price.

Comparison of all active prices:

Regular = $20.00

Buying group = $18.00

Autumn promotion = $19.00

Overstock 15% discount = $17.00

Lowest available = $17.00. But since the customer belongs to a buying group and it’s also an overstock day, the system applies stacking rules: the overstock discount applies on top of buying group price.

$18.00 × 0.85 = $15.30.

Create a Customer Discount Group

Create an Item Discount Group

Select the Item Discount Group for the Item

Comprehensive Detailed Explanation

To configure sales discounting in Dynamics 365 Business Central, you need to set up the relationship between customers and items so that the system can automatically apply the correct discounts during sales transactions. The process involves both customer grouping and item grouping.

1. Create a Customer Discount Group

This step defines which customers are eligible for group-based discounts (e.g., a retail chain, buying group, or brokers).

By creating a Customer Discount Group, you can later apply uniform discount rules across all customers belonging to that group, instead of configuring each customer individually.

2. Create an Item Discount Group

Next, you create Item Discount Groups to categorize items into discountable product lines (e.g., Olive Oils, Spices, Snacks).

This ensures that discount rules apply consistently across items in the same category, rather than having to define rules item by item.

3. Select the Item Discount Group for the Item

Finally, you link each relevant Item Card to the correct Item Discount Group.

This connection ensures that whenever a sales order/invoice is created for a customer belonging to a discount group and includes items in an item discount group, the system automatically applies the correct Sales Line Discounts.

Why not the other actions?

Define the Sales Invoice Discounts → Used for invoice-level discounts, but here the requirement is item/line-based discounting.

Define the Customer Special Sales Prices & Discounts → Used for customer-specific or promotional pricing, not for group-wide discount structures.

Configure Discount Posting in Sales & Receivable Setup → Relevant for accounting/reporting (whether discounts post separately) but not for setting up how discounts are determined and applied.

Define the Sales Line Discounts → This is the outcome of linking customer discount groups and item discount groups, but it requires the setup steps above first.

Special Prices and Discounts in Business Central

Comprehensive Detailed Explanation

The case study mentions reconciliation issues caused by manual entries being made directly into certain G/L accounts, which led to discrepancies between subledger balances (like customers, vendors, or inventory) and the General Ledger. To resolve this, Business Central allows you to restrict how accounts are posted.

Restrict use on → G/L Account Card

The most appropriate place to restrict usage of specific accounts (such as control accounts for A/R, A/P, or Inventory) is on the G/L Account Card.

Here, you can configure posting restrictions for each account individually (e.g., Accounts Receivable account should only be posted through the customer subledger, not by manual G/L journals).

Other options:

General Ledger Setup → Controls global accounting settings, not account-specific restrictions.

Sales & Receivable Setup → Defines control accounts but does not enforce restrictions.

Chart of Accounts → Displays accounts but restrictions are managed per account card.

Set value for → Direct posting

On the G/L Account Card, the field Direct Posting determines whether users can post manual entries directly into the account.

To prevent reconciliation issues, Direct Posting must be disabled (unchecked) for accounts controlled by subledgers (e.g., A/R, A/P, Inventory).

This ensures that postings only come from system-generated entries (like sales invoices, purchase invoices, or inventory adjustments) and not from manual journals that could break reconciliation.

Other options:

Reconciliation account → Relevant in SAP, not BC.

Check G/L account usage → Not a standard control in BC.

Gen. Posting Type → Defines how entries are posted (Sale, Purchase, Inventory), but does not enforce direct posting restrictions.

With this setup:

Reconciliation issues are avoided because control accounts cannot be posted to manually.

Users are guided to post through the proper subledger processes (sales, purchasing, inventory, etc.).

Financial integrity between subledgers and the G/L is maintained.
