Hi,

Thanks for your input. The version of BIDS reported when I go to Help About is:

Microsoft Visual Studio 2008

Version 9.0.30729.4462 QFE

Microsoft .NET Framework

Version 3.5 SP1

The report RDL was developed on this version of BIDS, it hasn't been converted.

I've attached the RDL file of the report (saved as a .TXT file).

No CU patches have been applied to out server.

The SSRS is running an SQL 2008 R2 and the report is pointing to the same server.

Cheers
