tax calculation invoice

[Willem]

Hello, 

We are in the process of learning the financial functionalities of ofbiz and 
have a question about the following: 

We want the sales tax automatically calculated on an invoice and separately 
displayed. 

We have set properties in productstore, taxauthority, tax geo, at the 
product, price and category level and it doesn't work.
Does anybody know where to find specific info on this subject or can tell 
which properties to configure? 

Your help is appreciated. 

Greetings,
Willem Janssen
