Microsoft distributes Microsoft SQL Server 2008 R2 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 R2 fix release.
When you preview a report in Report Designer for Business Intelligence Development Studio (BIDS) 2008 R2 on a computer that is running Microsoft SQL Server 2008 R2 Reporting Services, an RDL.DATA file is not created unexpectedly.
Note In earlier versions of BIDS, when you preview a report, BIDS creates an RDL.DATA file. The file caches the datasets for the report, can be used for troubleshooting, and can prevent frequent queries to the back-end server when you develop and test reports.
