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.

The company requires multiple number series for Raw Materials, WIP, and Finished Goods, with unique prefixes, selectable at item creation, and automatic assignment. In Dynamics 365 Business Central, number series are configured in a structured order:

Create a number series.

Define unique number series for each item type (e.g., RM-#### for Raw Materials, WIP-####, FG-####).

Specify starting/ending numbers and format.

Create relationships between the number series.

Relationships allow the user to select among multiple number series when creating an item.

This ensures that at item creation, the correct prefix (series) can be chosen.

Enable the ability to use default numbers.

On the number series setup, set Default Nos. = Yes to enable automatic numbering when a new item is created.

Set the default number series on the Inventory Setup page.

Finally, assign the relevant number series as the default for items in Inventory Setup.

This ensures automatic numbering, but still allows selection of other related series when needed.

This sequence satisfies all requirements:

Unique series per item type → Done in step 1.

Selectable at creation → Handled in step 2.

Automatic number assignment → Steps 3 and 4 ensure automation with flexibility.

Comprehensive Detailed Explanation

The Copy Company function in Business Central duplicates all data (setup, master data, historical entries, transactions) from one company to another within the same environment.

It is used for creating a sandbox/test company or making a copy of a live company, not for importing opening balances.

Since the requirement is to transfer only opening balances, this method does not meet the goal.

This sequence makes sense because you first create the series itself, then define the lines (the actual numbers within the series), and finally define the relationships to link the series to the specific data table (like the Accounts table) where it will be used.

Sequence 2: Using a Configuration Package to Manage Data

This sequence focuses on using a configuration package to manage and update data, which might include fixing issues with existing accounts or importing new ones.

Create a configuration package.

Configure the Vendor Table on the configuration package.

Create the Data template.

While this sequence is plausible, it has a significant flaw: the prompt mentions "Accounts," but this sequence specifically mentions the Vendor Table. If we assume the "Vendor Table" is a placeholder for a generic data table like the Accounts table, the sequence makes sense. You create a package, configure it for a specific table, and then create a data template to import the data into that table.

Sequence 3: Resolving Issues by Defining the Number Series on the Configuration Template

This sequence focuses on resolving issues by directly modifying the configuration template within a configuration package.

Create a configuration package.

Create the Data template.

Define the No. Series on the configuration template.

This sequence is logical for a scenario where you're using a configuration package to manage both data and its associated number series. You first create the package, then create the data template (which is a core component of the package), and finally define the number series on that template to ensure the imported data uses the correct number sequencing.

In BC, invoices can be generated from:

Sales Order Invoicing (D): Post invoices directly from sales orders.

Combine Shipments (A): Consolidate multiple shipments into a single invoice (used for customers who require weekly or monthly invoices).

Get Shipment Lines from Sales Order (B) is incorrect — shipment lines are retrieved in warehouse processing, not for invoicing.

Sales Order Shipping (C) posts shipment only, not invoices.

Get Shipment Lines from Sales Invoice (E) is used for service scenarios but is not the standard sales invoicing process here.

Correct: A and D

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.
