The feature: "The edition of Reporting Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database." is not supported in this edition of Reporting Services.

I have installed SQL Server 2014 Express Edition with Advanced Services, and I configure my report server on same server. When I create Data Source on report server, I gave connection string  like..

Data Source=remote_db_server;Initial Catalog=TestDB

Clicked on Test Connection button and getting error 

The feature: "The edition of Reporting Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database." is not supported in this edition of Reporting Services.

I am not able to figure out why I am getting this error.

Can any one please help me how can I solve this issue.

Thanks,

Vishwa.
