I am trying to onchange sale.order.line 's field (tax_id) and update sale.order 's field, is that even possible? I had tried:
value = {
'price_unit': '' ,
'x_istaxcode': True #custom field in sale.order (boolean)
}
return {'value': value}
Output:
price_unit of the sale order line become 0.00.
x_istaxcode is not changing.
Please advise.
