List of roles/tabs per user

Hi,

I am running EP6 SP13.

We have 150,000+ users on our portal. From a design perspective, I would like to make sure that no user has more tabs than can fit within their top-level navigation. Scrolling right/left across portal tabs makes the portal user interface difficult to use.

Is there a report available (or one I can create in ABAP or JAVA) to list the TABS showing on each portal user's desktop?

Thanks,

Kevin
