Steps to reproduce:

1- Create on order with products product 1 and product 2 having 10% discounts from a promotion programs

2- open point of sale and pay the order

3- try to get a refund on product 1

4- the refund will get the taxed price of product 1 pre discount, it doesnt take the discount into consideration

Did anyone encounter such a problem? How did you fix it? is there any module in the odoo apps that can fix this bug.

Thank you in advance.
