i. Please insert the following, to the Unsupported Reporting Services Features section of the article (it is an extract from: http://technet.microsoft.com/en-us/library/bb283186.aspx )
“A subscription that delivers a report to a library or to a shared folder creates a new, static file that is based on the original report, but it is not a true report definition that runs in the Report Viewer Web Part. If the original report has interactive features (such as drillthrough links) or dynamic content, those features will not be available in the static file that is delivered to the target location. If you select a "Web Page" you can preserve some interactivity, but because the document is not an .rdl file that runs in the Report Viewer, clicking through a report creates new pages in the browser session that you must scroll through to return to the site."
