If you are a BI platform manager  or BI administrator responsible for ensuring the proper implementation of your  organization's security model, or if you're involved in BI user support, then  you'll find administrative user impersonation to be an extremely useful feature  of APOS Administrator and APOS  Security Manager.
          User impersonation allows  administrators to see what specific users see, so you can examine the  implementation of your security model down to row-level security with more  certainty than you can creating temporary accounts. If you are providing BI  user support, user impersonation lets you experience precisely what the user is  seeing while you are talking to them remotely. You can log in to BI Launchpad  as the user and view reports just as that user would see them.
          Change validation using  administrative user impersonation can work with the user providing credentials,  or without user credentials if you activate the SAP BusinessObjects Trusted  Authentication feature.
