You must at least have one role or right on the organization or person in question, to be able to create a request.
How to do it:
When you open a form or a service you have no rights to, you can click on the button "Request access".
You can also request access by selecting the menu Profile, the sub-menu Forms and services you have rights to and then choosing the Create new request button. On the next page, search for the form or service you want access to.
This happend when delegating:
Those who can delegate rights to you will see your request when they log in. You will receive confirmation by e-mail from Altinn when the request has been accepted.
Unfortunately, you will not be notified if the request is rejected.
