Audience levels are defined by Campaign administrators to represent different potential targets of campaigns, such as account, customer, household, product, or business division. Audience levels are often, but not always, organized hierarchically. Here are some examples of hierarchical audience levels that are commonly found in customer marketing databases:
Audience levels are created and maintained by a Campaign administrator. Moving from one audience level to another requires that all of the audience levels that you use have keys defined within the same table. This provides a “look up” mechanism to switch from one level to another.
If you have permissions to map tables in Campaign, you can map a new table to one or more existing audience levels, but you cannot create new audience levels. Only users with the appropriate permissions, usually system administrators, can create audience levels.
