If you want to check how a report or dashboard runs as a different user but you haven't yet setup "ACT AS" functionality or you don't know the password of the user, you can pass the &impersonate variable trought the URL. (If you are logging in as Administrator)
Change this URL to the one shown below:
Directly in answers: http://vmobiee:9704/analytics/saw.dll?Answers&impersonate=OBIEE_A
where OBIEE_A is the username of the person you want to impersonate.
