Building a composite address locator

1. Create individual address locators.
2. Determine the input address fields for the composite locator. These are the fields to which the individual locators are mapped to find an address.
3. Specify the input field mapping of each locator's input address fields to the input address fields of the composite address locator.
4. Specify the selection criteria for the individual address locator if you want to specify the locator that is used for a particular address based on the criteria (optional).
5. Specify where to store the output composite address locator.
