How to cange default VAT rate in Billing module

How can I change the default VAT rate?
I found a thread saying to do this in MYSQL:

Code:

UPDATE invoice_item_template SET vat = 15 WHERE vat = 19;

However 0 rows are effected when I do that. Is that info out of date?

 

You must set the VAT for each item template in ISPConfig.
