Description
A field that contains an administrative zone, such as city, district, or postal code, in the reference data was not assigned to the locator role field in the Field Mapping parameter of the Create Locator tool. It is strongly recommended that you assign administrative zones when building a locator. Not mapping them can impact geocoding quality and the performance. For example, region and region abbreviation are used to help create different forms of state highways that are specific to each region or state.
Solution
Assign at least one field from the reference data that contains an administrative zone to at least one of the locator role administrative zone fields in the Field Mapping parameter.
