In the repair module if you invoice a product or service for which the price includes a tax (eg VAT) is it normal that the tax is still added ?
Ex.
1) in the 20% tax, You check it is included in the price
2) your service price is 100.00
3) in the RMA you have a line with ->
 service : tax 20% : price 100 and a total with -> Total without Tax 83.33: Tax 16.67 and TTL 100
But currently you have:
service : tax 20% : price 100 and a total with -> Total without Tax 100: Tax 20 and TTL 120

Normal Or a bug ? Coz in old Odoo 8 It worked well
