that's in fact a very good question. We had some confusion round here concerning that point for a long time - caused by our distribution_partner themselves who told us at some point that the difference between the types of CALs is ONLY the nr. of documents you can access.
A short while ago, we had the plan to introduce some "area_designers" who would be able to do minor edits on their one respective app, but that didn't work since they have only doc_CALs.
<=> Now we have been told that, as you rightly assume, with a doc_CAL, you can only
License Lease is only available to those users who have obtained a Named User CAL as this license type facilitates both online & offline (QlikView Desktop) use. Document CALs, Session CALs & Usage CALs are all online licenses only meaning the user must be connected to the server to analyze their data.
this is a correct bevaviour. With Named Cals you can open as many Apps you like at one time. AND, when opening with a Windows-Client you are able to develop QV-Apps, this means reloading and designing the graph user interface.
So they are normally for IT and Key-(Power-) User.
A Doc-Cal is assigned to one user and to one document. With it you can't develop like described above. Therefor it is much cheaper and used normally from Analysts.
