Hi, I have created a custom report which I want to load into SQL Server (by right clicking on the server name and adding the custom report). When I try to do this I get the following error: ------------------------------ An error occurred during local report processing. (Microsoft.ReportViewer.WinForms) ------------------------------ ADDITIONAL INFORMATION: The definition of the report 'Main Report' is invalid. (Microsoft.ReportViewer.Common) ------------------------------ The report definition is not valid. Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition' which cannot be upgraded. (Microsoft.ReportViewer.Common)------------------------------ The report was built using BIDS 2008 and the report is run in SQL Server 2008. I have no idea what this means or how to resolve it. Can someone please help explain to me what this means and how I can resolve it thereby loading the custom report into SSMS? Many thanks, Richard
