So I developed a report in Report Builder 3.0, but when it posted to SSRS 2008. I get the follow message about a read/write variable I have.
The Writeable property of variable, CostCodes, is set to true. SQL Server 2008 Reporting Services does not support variables that are read/write. Either make the variable read-only or change the TargetServerVersion to a version that supports the read/write variables.
So two questions, what version do we need to be on to support read/write variables? Second, is there a work around for SSRS 2008?
