Hi,
I know how to define a new tax and the tax calculation on purchase order and sale order. I would like to know what are tax codes and taxes with regard to openerp 7, and by default there are 23 tax codes and few taxes (OTAX S,OTAX R,OTAX X,ITAX S,ITAX R,ITAX X). What are they and i thought of remove all those taxes. Will there be any problem if i remove it. I wanted to learn more about it and googled and got the following link
https://doc.openerp.com/6.1/pl/book/3/3_9/tax_structure/
But it's not working. If possible provide some links too. Thanks for your time :)
