Message Types 

The message types have been defined by the programmers, not the Ergonomics Group.

S Message (Success)

S-type messages are displayed in the Status Bar on the same or next screen. The message has no influence on the user's work. It only confirms the successful execution of system functions.

I Message (Information)

This message has a modal character - that is, the user must acknowledge the message. I messages are therefore displayed in a modal dialog box. The processing can be continued by pressing the ENTER key.

W Message (Warning)

So-called W messages interrupt the processing and allow the user to make corrections. For this reason, fields are enabled for input. W messages are displayed in the Status Bar if the messages have been issued by a primary window. If a dialog box issues the message, the system displays the message in a separate dialog box.

With regard to the system response, warnings are similar to E messages. E messages, however, force the user to change the entry.

E Message (Error)

When the system detects an error, E messages should be used. Incorrectly completed fields must be ready for input. If consequential errors occur, we recommend to make not only the incorrectly filled field ready for input but also those fields whose entries have contributed to the error.

Depending on whether the E message was issued by a primary window or a dialog box, it is either displayed in the Status Bar of the primary window or in a separate dialog box.

A Message (Abend)

A messages are intrinsically of a modal character, that is, a separate dialog is inserted into the current task. Therefore, they are displayed in modal dialog boxes.

A messages do not allow the user to make any further entries. The user can only acknowledge the message. The task is abruptly terminated and the system returns to a higher-level menu.

A messages should only be issued in extraordinary circumstances, for example, when a system-related error occurs or if the error can no longer be handled by the task. In all error situations handled by the task, however, it should be possible for the user to remain in his work environment. A messages should therefore be avoided, if possible.

Icons in Messages

If standard error messages from the Basis system are displayed in a dilaog box, the system auotmatically displays the appropriate icon for the particluar message type (E, W, I, or A). Since S messages always appear in the status bar, there is no icon for S messages.

In general, application developers do not have to take action in this respect.
