Usability objects must be enabled
In addition to providing the standard reporting and search capabilities, Unica Discover Usability events are also used by the usability application itself. For example, when the Discover user chooses to display the Form Analytics overlay in Browser Based Replay, the usability components in Replay query the Reporting database for the event data that pertains to form analysis for the current page or ScreenView.
Note: For correct capture and display of usability data in the Unica Discover
Usability overlays in Replay, all hit attributes, events,
and dimensions must be enabled through the Event Manager. By default, these objects
are installed and enabled. Disabling can disable usability functions and
data.
