Hi,

I am trying to validate credit limit of customer when click on Confirm button in sale.order view

A warning is showed when self.amount_total > partner.credit_limit * 80%, however it is not block the working flow

Here is my source code

@api.one
def show_credit_warning(self, total, credit_limit):
    if total > credit_limit * 0.8:
        message = _('Message content')
        warning_mess = {
            'title': _('Credit limit is over 80%!'),
            'message': message
        }
        return {'warning': warning_mess}
    return {}

@api.multi
def action_confirm(self):
    self.ensure_one()

    # Check credit limit
    partner = self.partner_id    

    if self.amount_total > partner.credit_limit:
        # Block when over 100%
        raise exceptions.ValidationError(
            _('Credit Limit Exceeded! You need to increase the credit limit of this customer to proceed'))
    else:
        # Show warning when over 80% credit limit
        # TODO: Not work, display nothing here
        self.show_credit_warning(self.amount_total, partner.credit_limit)

        res = super(SaleOrder, self).action_confirm()
        return res

Thank you for your help!
