The SSRS 2008 R2 release in SharePoint mode allows two forms of reporting:
- Out-of-the-box (OOTB) Local mode reporting: In this case, SSRS 2008 R2 introduces the ability to render reports without an integrated Report server. Details on local mode reporting with SharePoint integration can be found @ http://msdn.microsoft.com/en-us/library/ff487969(v=SQL.105).aspx. From an install prespective you only need to install SSRS 2008 R2 RTM Add-in for SharePoint 2010 on SharePoint 2010 RTM Web-front-end(s) to have the ability to render uploaded / canned reports (.rdl files) for:
- SharePoint Lists reports: available in SharePoint 2010 Foundation Editions or higher.
- Access reports: available in SharePoint 2010 Editions that Access Services is supported in.
Point to note: You need to turn on ASP.Net Session state as well, by opening the SharePoint Management Shell and entering the command - Enable-SPSessionStateService. Next, the command will ask for a DatabaseName value that you can provide say "MySessionDB". Finally, perform an IIS reset.
- Connected mode Reporting: This form of reporting is allowed when you have an SSRS Report Server integrated into the SharePoint farm as well to enable full end-to-end reporting that existed in prior versions and is now available in SharePoint 2010 with the SSRS R2 RTM Add-in for SharePoint 2010.
