Some address locator styles may require more than one table, such as US Streets with AltName. The Primary table usually requires a feature class and an Alternate name table, which are in the same geodatabase. An Alias table is for the place-name aliases. Each table should be specified accordingly with the correct type of role.
Choose the correct feature class or tables and assign the role (Primary table, Alternate name table, or Alias table).
Choose a feature class that does not participate in a join ,or export the feature class with the joined data to a new feature class and choose the new feature class as the reference data.
