After publishing, you can go to the online service and Save As to create a duplicate of an existing report. Then you can delete tabs, add tabs, change visuals, etc. It is still connected to the same data source, so you won't have to set up a separate refresh schedule, and any future updates to the original (re-publishing with new measures for example) will be reflected in any derived reports. So usually when I publish a report, it's primarily meant for a division director or mid-level person who needs a whole bunch of details, but I also need an "executive" version of the same report for the VPs and CEO and whatnot. So I publish the primary report, then Save As "Blah Blah Executive Report" and prune it down to just what they need to see.
