Invalid Target Namespace When Deploying a Report to SQLServer 2008

If you get an error like the following when deploying a report to SQLServer ReportingServices 2008, it is usually because the report was created in a design environment setup for SQL Server 2008 R2, but your server is SQL Server 2008 R1 (I know, that’s not what it’s called, but you know what I mean).

The report definition is not valid. Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition' which cannot be upgraded. (rsInvalidReportDefinition)

To fix this error:

• Edit the report RDL (Code View as it is called in BIDS).
• Replace the Report header with the following:

  <Report xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner" 
  xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition">
  
  

  
  
• Remove the <ReportSections> and <ReportSection> tags from the report. Note, remove the tags only.  Leave all content inside the tag.  Don’t forget to remove the closing tags for each of these.
  
• Save the report.  You should now be able to upload it.
