Make sure the visibility attribute is true

Hello Hilar,

Thanks for the response. it should be visible because in web view, the column is there. Only in mobile view that it did not load the filed/column. Please review my code.

class SalesOrderLine(models.Model):

_inherit = 'sale.order.line'

# calculate uom qty / packaging

@api.onchange('product_uom_qty')

def _calculate_pcs_box(self):

for data in self:

if data.product_packaging:

self.product_packaging_qty = data.product_uom_qty / data.product_packaging.qty

product_packaging_qty = fields.Float(string='Package Quantity', descriptio="Field for packaging qty")

<xpath expr="//tree/field[@name='name']" position="after" >

<field name="product_packaging_qty" optional="show"

groups="product.group_stock_packaging"/>

</xpath>
