The requirement is to resolve the order entry issue:

“Customers often reorder the same items with similar quantities. The system must be configured to ask the user if recurring lines should be added to sales orders.”

Business Central has Standard (Recurring) Sales Lines functionality to address this.

Configure standard sales lines → Add items and quantities

Standard sales lines define templates of frequently ordered items and their quantities.

When configuring these, you specify which items and quantities belong to the recurring order.

This resolves the need to avoid retyping common order combinations.

Add recurring sales lines to customers → Set insert on orders to Always Ask

On the Customer Card, you assign the standard sales lines and configure how they should be inserted when creating sales orders.

The setting Always Ask prompts the user each time an order is created for that customer, allowing them to choose whether to insert the recurring sales lines.

This satisfies the requirement to “ask the user if recurring lines should be added.”

Why not other options?

Add valid from and to dates – Useful for time-limited campaigns, but not mentioned in the requirement.

Set insert on quotes to Automatic – Applies to sales quotes, not orders. The requirement specifically concerns sales orders.
