I deploy a report solution from Visual Studio report builder and upload several reports onto SSRS.
I try my connection but failed and other previous reports which used different connection setting worked.
Please see below the two connection settings: The first figure is mine and the second figure is others'. The only difference is the 'Data Source' in 'Connection String'. Can you please advice why this cause the problem and how I can fix it? If I use 'localhost' to create my data source in my local desktop, the report cannot be compiled successfully.
