Screen Design Components

The following list describes the functions of the major components that you create and modify in the process of designing a screen:

A field implements import and export data views. A single screen associated with each procedure step is responsible for providing data to its import view and displaying data from its export view. As a designer, you can use each field on the screen to implement both an import and an export view of an attribute.
Note: Before you begin to add fields to screens, be sure you understand the relationship between screen fields and import and export data views.
A literal is information that does not change such as the title appearing at the top of a screen. Presented as text, number, or symbol, a literal represents itself rather than a reference to something else.
A prompt is a label for a field or a special field. A prompt is placed close to the field with which it is associated.
A special field reflects a special attribute that is not derived from business requirements but is introduced during system design for a specific purpose. Examples of special fields are user IDs, timestamps, transaction codes, and system error messages.
A template can also be part of a screen. It can consist of literals, prompts, and special fields.
