There is bug in SQL Azure Reporting Services CTP where reports that take longer than 1 minute to execute are being killed by Windows Azure as "idle connections", see http://social.msdn.microsoft.com/Forums/en-US/ssdsgetstarted/thread/9d43af1a-0100-4f4c-9166-9702776d0d43/
Most of the complex reports take more than a minute to execute. Hence the need arises to be able to deploy the report on an On-Premise SQL Server Reporting Service. However, if try to deploy a SQL Azure Report on an On-Premise SQL Server Reporting Service you will see the error “An attempt has been made to use a data extension 'SQLAZURE' that is either not registered for this report server”
Below are the steps which can be followed to deploy a SQL Azure Report on an On-Premise SQL Server Reporting Service:
