title: SSRS 2008 Credentials used to run this report are not stored
body: <p>I created a report in SSRS, and deployed it. I went to the properties of the report the Process option, and tried to set up Cache a temporary copy of the report and got an error 'Credentials used to run this report are not stored.' I get the same error if I go to Snapshot Options and try to select any of the options there.</p>
  
  <p>Thanks in advance</p>
