You're on the right track with your current setup using the sale_packaging_default module. It’s great that Odoo is showing “48 units (2 box)” - that means the packaging configuration is working as intended.

To achieve your desired output of mixed packaging display like:

40 units (1 box + 16 pieces)

…you’d need a bit of customization in the QWeb report templates and a small addition in the compute logic for how packaging is represented.

✅ Here's how you can do it:

1. Custom Compute Method

Create a custom computed field (inherited on sale.order.line) to store a "packaging breakdown" string.

Example Python logic (in a custom module):

from odoo import models, fields, api

class SaleOrderLine(models.Model):

    _inherit = 'sale.order.line'

    packaging_info = fields.Char(string="Packaging Info", compute="_compute_packaging_info")

    @api.depends('product_uom_qty', 'product_id')

    def _compute_packaging_info(self):

        for line in self:

            if line.product_id and line.product_id.packaging_ids:

                # Assume box packaging is defined

                box_pack = line.product_id.packaging_ids.filtered(lambda p: 'box' in p.name.lower())

                if box_pack:

                    box_qty = int(line.product_uom_qty // box_pack.qty)

                    rem_qty = int(line.product_uom_qty % box_pack.qty)

                    if box_qty > 0 or rem_qty > 0:

                        line.packaging_info = f"{int(line.product_uom_qty)} units ({box_qty} box + {rem_qty} pieces)"

                    else:

                        line.packaging_info = f"{int(line.product_uom_qty)} units"

                else:

                    line.packaging_info = f"{int(line.product_uom_qty)} units"

2. Customize QWeb Reports

Now in your QWeb report (like sale.order, stock.picking, or account.move), use XPath to replace the default quantity field with this new packaging_info field.
