When a new Source is defined it must be associated with a new web application Url for reporting purposes. In the case of applications like web sites or hosted software this is simply the Url of the application your users would access it by. But, if your application is not web based you still need to define a Url / Description for your application to enable reporting.
Adding new web application meta-data is currently only available via SQL script direct into the NGAGE Analytics Server Database.
