The onchange/inverse would only be triggered in the case of manual document number (vendor bills)
or not highest_name, but in other localizations there are cases where we want to be more flexible
to when we change it and instead of inheriting the method, we can relax it here.
Also, it should have been avoided before already to change the document number and type in those situations
through the attributes in the view e.g. This seems to have been more like an extra fail-safe blocking us
elsewhere.
