Domains Data Lookup

The data lookup option from the Domains screen accesses the Data Lookup overlay, shown in Figure 2-3-2, where you can identify an application, file, and key field that can be accessed by using the value in any field referencing this domain. The key field must be a primary or alternate key to the file. This entry establishes the Data Lookup specifications for all fields that reference the domain. Upon completion, you are returned to the Domains screen.
