[Resolved] Rounding by Ticket Total Exactly Type!

hmm… OK I understand what is going on and why it works fine on test version.

If it is already setup can you try this one ? A little math magic that assumes 0.05 is 1/20

result = (round up (Ticket.PSum + Ticket.PreSum + Ticket.Tax) * 20)/20 - (Ticket.PSum + Ticket.PreSum + Ticket.Tax)
