Sometimes when we create the ticket in the pos module of odoo (v10) and the client decides to pay with a credit card, later he changes his mind and decides to pay with cash or vv. We have already advanced to the print receipt screen.
I assume the pos_order is already in the paid state at this time, right? Iow, once the VALIDATE button is clicked in the payment method screen, the pos_order is considered paid, right?
the best way is to cancel the first ticket (using the minus sign in front of the quantities) and the create a new one.
The other way is to make an accounting entry (miscellaneous journal for instance) where your credit the petty cash and devit the credit card account
Yes i know i can eliminate the ticket with the minus sign, the problem is that that order already will appear as part of the day's sales report.
