Report Builder 3.0, failed to on test connection and preview-Collection of common programming errors

Hi SevenKnights,

when i install SSRS, i already need to specified whether to run as Native mode or Sharepoint integrated mode. Base on our implementation, we need to run on integration mode. Therefore i have not tried to setup in Native mode first to test whether Report builder 3.0 is working fine. but directly install SSRS on integrated mode.

if i run report builder 3.0 standalone client without connecting to sharepoint, i can create data source, test connection without any problem. Once i connect to sharepoint url,  and goes to the build data connectoin and hit test connection, it show successful, but once i back to the build dialog box and hit the test connection, i’m getting “Specified method is not supported”. if i ignore this error, it still show the remote tables on the query designer and i can drag-and-drop fields. once the report had been generated if i run preview, i’l get “Specified method is not supported”.  If i deploy this report onto Sharepoint document library, and click on the report, it can shown the report with data populated without problem.
