Under the Cognos Configuration->Data Access->Content Manager Tab there is an option to save report outputs to a file system.
If i change this to yes, where would i look to find the reports outputs saved?
Requires a custom parameter entry named CM.OutPutLocation that has a value that is a valid path. You can also save report outputs outside of Cognos but the method varies depending on your version.
Check these docs out if you can (search page for "Saving Report Outputs to a File System")
