Audience level unique identifiers

When you create a new audience level, you must specify at least one field to be used as the unique identifier for members of that audience level. To uniquely identify each member of the audience, you might need to use multiple fields.

For example:

  • Household could be identified by the field HHold_ID
  • Customer could be identified by the fields HHold_ID and MemberNum.

The field names (and in particular any unique identifier field names) in the new audience level must exactly match the field name(s) in the database table for history mapping. This allows Audience Central to automatically match the database fields to the appropriate system table fields when you create the history table mapping.

Note: Audience level field names have specific character restrictions.
