Securing two universes.

Hi everyone,

I would like to know how to secure users who have access to two different universes.

For example,

userABC only has to run reports on a HR universe but he has to create Web Intelligence document on a Financial universe.

If he has permission to create Web Intelligence documents and needs to have access to refresh the HR data, how can we manage the security to prevent him to create a WebI document with the HR data.

Thanks for your help.
