问题
I use VS2015 with SQL Server Data Tools; I have some Reporting Services (RDL) reports.
I want to deploy them to a Reporting Server with SQL Server 2014 installed.
In my report project I set the TargetServerVersion to "SQL Server 2008R2, 2012 or 2014", but the deploment process fails with an error similar to:
Report Definition invalid, because namespace .../2016/... invalid.
回答1:
It is solved. You "MUST" recompile your report project and immediately afterwards you can deploy your reports without any problem.
