Real-time profiling allows you to view and use characteristics of a selected field. It can affect performance, however, when working with large databases. For this reason, Campaign allows this option to be disabled.

When real-time profiling is disabled, and you click Profile, the Profile Selected Field window appears, but a message is displayed at the bottom of the window to indicate that real-time profiling is disallowed.

If profiling is disallowed and the field is not configured to be pre-computed, the Profile Selected Field window indicates that no data is available, no counts or categories are displayed, and all Statistics counts are zero.

For more information about disallowing real-time profiling, see the IBM® Unica Campaign Administrator's Guide.
