Sections allow you to better sort and assess Profiles from your different domains in Audience.

Expand the Section drop-down menu in Audience to change Sections.

Not all Users in APSIS One will have access to all Sections. This depends on your User Role and specific Section permissions.

Also, when creating an activity in APSIS One, you will often notice the option to select a Section.

If you only have visibility to one Section, you may not see this drop-down. Make sure that you select the correct Section so that the right data is available when creating your activity.

If you can't see the Section you're looking for, reach out to your account's Admin User or Account Owner to adjust your permissions.
