Domain Fields (System Domains)

The Domain-type field specification overlay, shown in Figure 2-4-15, displays after you select enter from the fields screen if the Field Type you select is DOMAIN and the domain type is system.

Figure 2-4-15. Domain Field Specification Overlay (System Domain)

The following fields are contained on the Domain Field Specifications overlay for system Domains:

·    Domain Name links a domain-type field to a specific domain in the same or another APPX application.

·    Descriptive provides a longer, more easily understood alternative to Field Name, one that is not required to be unique within an application. If blank at all default levels, Field Name is used. Refer to the definition of Descriptive in the Domain Fields section for more information.

·    Column Hdgs designates up to two lines of column heading text. The APPX output process facility uses this text to generate standard column heading images for Start of Page and Start of Range class frames. For cosmetic reasons, the length of headings should not exceed the length of a field itself. Refer to Standard Column Heading Image for additional information.

·    System Type — An System domain can be used to identify the user ID of the operator who adds or modifies a record in the database. The System Type options are USER ADDED, which identifies the user ID of the operator who added the record; USER CHANGED, which identifies the user ID of the operator who modified the record; DATE ADDED, which identifies the date that the record was added; and DATE CHANGED, which identifies the date the record was last modified.

The Additional Attributes option accesses the Additional Attributes overlay which contains only one field:

·    Use Domain Doc? Toggle the checkbox between “yes” if you want APPX to use the documentation from the domain as Help text and “no” if you plan to enter Help text unique to this field.
