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.
