title: Can not find the existing data source for the SSRS report
body: <p>I am trying to create a SSRS report with sql server 2005 BI. I have to use the existing data source to be consistent with the other reports, but in the SharedDataSources folder when I click add existing item, I cant find the Data source.
  Can someone tell me where the Data Sources for SSRS reports store physically on a machine?</p>
  
  <p>Thanks</p>
