Good morning to everybody,
I'd like to know if someone has already found this bug and has solved it, I'm explaing the matter now.
N.B. The site is a B2B and the inserted prices are list prices with customer's discount that changes according the group which they belong to and net prices.(TAX ecluded).
I made 3 customers groups (beyond the default groups)
A 47% discount group
A 50% discount group
A 50+5% discount group
Everything is ok, it works. No problems.
The problem arises when I have to handle the extra discounts about the quantities of the single item since every item, reached a certain level, enjoys un additional discount by using the specific prices managing.
