I have an open receipt for 20 units. I only received 2 units from the vendor, so I validate the receipt for 2 units and create a backorder for 8 units. Eventually, these 2 units were returned to the vendor since they had quality issues. The units will be replaced by the vendor when the vendor ships the remaining quantity open. After I complete the return process in Odoo, I would expect the backorder quantity to update automatically back to the original demand of 20 units.
Since this is not the case, how do I account for the 2 units from the initial partial shipment? I tried creating a new receipt but it was not linked to the original purchase order.
