We have recently upgraded to SQL 2008 R2 including Reporting Services Server. All of the reports that we used to run on SQL 2005 Reporting Services work fine but we are experiencing export functionality issues. The reports are grouped and on screen, they appear ok, the drill downs work without any issues, once we save these into Excel, the drill downs behave very strangely including all drill downs are expanded or duplicate entries. This was not an issue with SQL Server 2005, only since the recent upgrade. Not sure if anyone has experienced similar issues or whether there is anything with Microsoft atm that would indicate that this is a know issue.
Many thanks in anticipation
