Hello,
i have configured standard purchase taxes as default, for some items, the taxes is differed from standard, so for those items, i configured item taxes, when i purchase them, the standard taxes show in the purchasing order, marked in red, i don’t want it;
I’m not sure from your description, but it sounds like you need to exclude the non-standard products
from the purchase tax rule “VAT - L”. You should be able to do this will item groups.
@volkswagner ,
sorry that i did not make it clear, let say item A has a special tax rate, so i configured a special tax rate for it, i also configured a default tax rate for common items, so when i purchased item A , both tax rates appear, actually i only need the special tax rate, so when this happened, i have to manually delete the standard tax rate
