During design, an exit state can be associated with a message that appears on the display.
It is wise to establish standard exit state definitions for outcomes or results common to many procedures, most notably successful outcomes.
For example, if processing was successful, a procedure might set the exit state to REQUESTED OPERATION COMPLETE. However, if a problem is detected, such as an invalid value entered for the command special attribute, the outcome might be INVALID COMMAND.
Exit state definitions are shared across all the business systems and business areas defined in a single model.
