Since now, there was no possibilities to pay a Sale Order in a point of sale without re-encoding every lines of the sale order in a pos order. So we've now added the possibility to choose a sale order from the point of sale, and apply a down payment or settle the selected order. You still get the possibility to invoice it, and the stock is correctly managed. The SO is then updated accordingly to what have been done throught the POS. closes odoo/odoo#74096 Task-id: 2500902 Signed-off-by: pimodoo <pimodoo@users.noreply.github.com>
