Contact history tables, which must exist in the Campaign system database, store historical contacts for each audience level.
The Customer audience level is delivered as an example, and the history of contacts targeting customers can be stored in the
UA_ContactHistory in the
Campaign system database. Detailed history for the
Customer audience level can be stored in the
UA_DtlContactHist table.
After you create the tables in the Campaign system database for a new audience level, you must map the new tables for the audience level’s contact history and detailed contact history.
