is there a way to add an event handler which handles an onchange event on input text. I need to put constraint on the invoice line where the user shouldn't fill a quantity greater than the value in the text box.

<field name="quantity" event="onchange(this)"/> onchange(){ console.log.. }

Hi Salim,
You can achieve the same from python code as follows. If you already knows it and looking for js please neglect it.
@api.constrains('field_id_of_quantity')
def check_quantity(self):
if self.field_id_of_quantity > self.check_field:
raise ValidationError(_('Quantity must not be greater'))
Dear Niyas, thank you and the api.constrains works, but in my case I prefer to validate the quantity in place because the @contrains will do it after clicking button action of the Wizard. Note that the @api.onchange failed to read the original data of the Wizard (I have a tree: product lines), that's why I'm looking for other solution.
