Message processing depends on the message type specified in the MESSAGE statement, and the program context in which the statement occurs.

Message Types

A

Termination

The message appears in a dialog box, and the program terminates. When the user has confirmed the message, control returns to the next-highest area menu.

E

Error

Depending on the program context

, an error dialog appears or the program terminates.

I

Information

The message appears in a dialog box. Once the user has confirmed the message, the program continues immediately after the MESSAGE statement.

S

Status

The program continues normally after the MESSAGE statement, and the message is displayed in the status bar of the next screen.

W

Warning

Depending on the program context

, an error dialog appears or the program terminates.

X

Exit

No message is displayed, and the program terminates with a short dump. Program terminations with a short dump normally only occur when a runtime error occurs. Message type X allows you to force a program termination. The short dump contains the message ID.

Contexts

Messages, especially those with type E or W, are processed according to the context in which they occur. The following sections summarize the most important context rules:

Messages Without Screens

Messages on Screens

Messages on Selection Screens

Messages on Lists

Messages in Function Modules and Methods

The program DEMO_MESSAGES demonstrates how the different message types are processed in different contexts.
