Webtrends Analytics 9 Adminstration Guide, November 2012
If you enable the Visitor History feature in the profile settings, you can incorporate Visitor History data using preconfigured custom reports.
Each behavior category you enable corresponds to preconfigured Visitor History reports. For example, to use the Sales By Most Recent Campaign reports in your profile, enable Visitor History in the profile, and select the Campaign History behavior. Then edit the profile and apply the Sales By Most Recent Campaign report on the Reports dialog.
The following tables shows the generated Visitor History query parameters, how the generated query parameters are used, and the preconfigured custom reports that are affected when you select that behavior category in the Visitor History dialog.
