Thanks for your help.

Here is the code to update delivery Qty. Who can help to fix it. Thank you.

    @api.multi
    @api.depends('move_ids.state', 'move_ids.scrapped', 'move_ids.product_uom_qty', 'move_ids.product_uom')
    def _compute_qty_delivered(self):
        super(SaleOrderLine, self)._compute_qty_delivered()

        for line in self:  # TODO: maybe one day, this should be done in SQL for performance sake
            if line.qty_delivered_method == 'stock_move':
                qty = 0.0
                for move in line.move_ids.filtered(lambda r: r.state == 'done' and not r.scrapped and line.product_id == r.product_id):
                    if move.location_dest_id.usage == "customer":
                        if not move.origin_returned_move_id or (move.origin_returned_move_id and move.to_refund):
                            qty += move.product_uom._compute_quantity(move.product_uom_qty, line.product_uom)
                    elif move.location_dest_id.usage != "customer" and move.to_refund:
                        qty -= move.product_uom._compute_quantity(move.product_uom_qty, line.product_uom)
                line.qty_delivered = qty

The relationship between bottles and case as you mention is 4 bottles = 1. case.

In this relationship, when 4 bottles are ordered 1 case was delivered, there are no bottles. Hence the return is only for case.

With your relationship a case can be directly sold.

If your product is ‘Wine with case’ then the KiT BoM components would need to be 4 bottles and 1 case.

This would create delivery of 4 bottles and 1 case, subsequently bottles and or case can returned.

Not sure if my understanding of your product to sell is accurate.

Hi,

Please refer to the module:

1. https://apps.odoo.com/apps/modules/18.0/sale_line_returned_qty_mrp

This module improves how returned quantities are computed on sales order lines when using Kit BOMs.

Hope it helps
