How can i display all the serial number of one product I'm using odoo 9 and i'm using the tracking by serial number. In sale or purchase when i do my delivery i want odoo displays all the serial number of one product for exemple i have a product x in my stock (80) in my delivery i want to transfer 40 units of that product , odoo displays only 40 not 80 . I do some research i found that odoo use FIFO to display the serial number. Is there a solution to modify the FIFO stratigy in order to displays all the serial numbers
