NAV 2013 - License Type

Dear Expert,

I want to test Limit User in NAV 2013. What exactly limit in NAV 2013?

My license have 3 limit user and 20 Full User, i try to create 1 user with license type is Limit User, so the result is:

-  I can create & modify Master Data.

- Post Journal, Sales Order, Purchase Order.

- Can view the history like General Ledger Entry, Value Entry...

- Can create & modify add-on table, page.

So I don't know the limit of this license type.
