The discount on the sales order line does not apply automatically during line creation or after recalculating without opening the Retail Attributes form.

When the customer adds a line and clicks Recalculate, the price remains unchanged.

However, after opening the Retail Attributes form (without modifying any values) and then recalculating, the discount is successfully applied as the discount is based on sales line attributes

This manual step needs to be repeated for each sales order line, which impacts efficiency.
