Analysis (custom) reports and Excel Comparison Table reports are set up in MI:Viewer and then submitted to a job queue, where the report is run in the background.
To allow MI:Viewer users to submit reports from the Reports page, the Service Layer URL must be specified as an application configuration setting. This URL is used:
This must be an absolute URL; relative URLs (e.g. including “localhost” or the 127.0.0.1 loopback) are not permitted here.
The specified URL is stored in the MI:Viewer configuration file appSettings.config, In a typical installation, this file is located here:
C:\Inetpub\wwwroot\mi\App_Data\config\WebConfigFragments\appSettings.config
Note that this configuration settings can also be specified via the MI:Viewer Configuration tool (Options>Configure Reporting).
