Pricing: Best way to determine an partial condition amount

Hi,

In our scenario MWST (VAT) is calculated from multiple values/conditions (price and postage&package costs).

What is the best way to extract the VAT value for only one of these conditions? I can only think of extracting this value via ABAP within a routine however this value isn't rounded? Is there a more easy way via customizing/conditions to extract this value?

We need this value to calculate/sum the net-value for postage and package costs.

Kind regards,

Tim
