When you define a user segment, you are defining a target audience. Self Service uses user segments to:
Set field security on global fields
Set list value security on list field values
Set value security on the intrinsic fields Owning Group, Internal Audience, and External Audiences
Identify targeted content displayed on Self Service sites
For information on creating user segments, refer to the ATG Business Control Center Administration and Development Guide.
Note: Anonymous users default to “female.” When creating a segment that looks for female users, anonymous users will be included in the segment.
