i'm looking for a solution for this situation: we have a product which is a booklet of 20 bus tickets. Tickets belonging to the booklet cannot be sold individually (the sale price refers to the entire booklet). But when the booklet is loaded in the warehouse, transferred between warehouses and then sold, the individual tickets belonging to the booklet must be tracked, each with its unique serial number. Anyone know if there is already an addon with this implementation? We use Odoo 14.
