Hello Maria - allow me to try an help you. I have some information that can help clarify how this is done.
Do you have the Distribution Service also known as Publisher?
I will also move this discussion to the appropriate thread. Stand by as I located this information for you.

In the QlikView Management Console (QMC) - click help - and look for Documents in the TOC on the left. Here it will describe the difference between Source Documents and User Documents. Configuration may vary if you have Publisher installed. If you do not have Publisher you can mount folders in the QMC where you will copy your .QVWs to. Security via the NTFS operating system OR QlikView can be configured which can control access to these files.
Let us know how you make out.

In regards to User Names - these are created in your Windows Operating system interface. Depending on the number of CALs you have, these will automatically be used as each user logs in. Depending on how your security is setup in QlikView - NTFS or DMS - you would either use the Windows File Permissions interface or the QlikView Management Console to setup access permissions.
