Hi ,
To achieve this you can super the function of the validate button and can add the validations.
class AccountInvoiceInherit(models.Model):
_inherit = 'account.invoice'
@api.multi
def action_invoice_open(self, vals):
# check here and add the validations
res = super(AccountInvoiceInherit, self).action_invoice_open(vals)
return res
what is the validation ?
