Zbik, thank you so much.

This did the trick: See master menu Settings: /Settings/Technical/Database Structure/Decimal Accuracy/Product Unit of Measure

It is really easy and works like a charm! Thanks to everybody for helping!

I use this in my QWeb reports to show a quantity of 1:

Changes the decimal for UoM to no decimal.

<span t-esc="'{0:,.0f}'.format(int(o.product_qty))"/> 

0f is saying zero decimals.  1f would be one decimal place, etc.  I hope this points you in the right direction.

Hi Peter,

Yes, default qty is displayed with 3 decimals, like you said, 1.000,

If you want to display 1 only instead of 1.000 you need to set decimal precision on that field by using "digits" property of the field

E. g.

from odoo import fields, models
class SaleOrderLine(models.Model):
    inherit = 'sale.order.line'
    product_uom_qty = fields.Float(string='Quantity', digits=(16, 0), required=True, default=1)

digits =  (16,0) is value for your present need, you can give the value according to your need, you needed 1.0 change it to (16,1) if needed 1.00 then change it to (16,2).

Hope this would help you.

Rgds,

Anil
