I'm creating new reports which should include several reports from different report servers as subreports. When doing this I'm referencing each report by a full path like http://server1/ReportServer?/LegacyReports/Sales Report
This gives an error:
An error occured during local report processing. An unexpected error occured in Report Processing. An error occurred during local report processing. Error in the application. Illegal characters in path.
What is a correct way to reference reports from another server?
