How should a surcharge be calculated based on a predefined subtotal in the pricing configuration?

The correct choice involves maintaining the condition subtotal at the reference step level within the pricing procedure, which is essential for calculating surcharges accurately based on a predefined subtotal. This approach allows the pricing procedure to reference the subtotal for subsequent calculations, ensuring that any surcharges, discounts, or additional pricing conditions can be derived from a consistent and relevant financial baseline.

This method enhances the pricing strategy by linking the surcharge directly to a specific point in the pricing structure, which makes it more adaptable to changes in other pricing elements, ensuring that the surcharge reflects current sales and pricing conditions dynamically.

Other strategies, such as setting the surcharge to a fixed amount or using the previous year's subtotal, do not provide the necessary flexibility to accommodate ongoing changes in pricing dynamics which may occur. Calculating it as a percentage of the total invoice amount may also detract from the specific context of applying surcharges based on predefined subtotals, as it does not necessarily relate directly back to the structured pricing logic that is established in the pricing procedure.
