AUGUST 7

Messages in SAP:
Messages are usually used to tell the user what is going on. The following types of messages are available in ABAP.

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

The syntax for issuing a message is as follows.

MESSAGE  <message> TYPE <message_type>.

We can issue a status message as follows. Status message will be displayed in the status bar. After the message is displayed the program continues after the MESSAGE statement.

Example:

MESSAGE  'This is a status message'   TYPE   'S'.

Output:

Information message will be displayed in a dialog box. Once the user has confirmed the message, the program continues immediately after the MESSAGE statement.

Example:

MESSAGE  'This is an information message'   TYPE 'I'.

Output:

Error message in report programs will be displayed in the status bar and when the user press enter, the program terminates.

Example:

MESSAGE  'This is an error message'  TYPE   'E'.

Warning message behaves similar to error message in report programs.

Termination 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.

Example:

MESSAGE  'This is a termination message' TYPE 'A'.

Output:

Exit Message – No message is displayed, and the program terminates with a short dump. Short dumps can be viewed in t-code ST22.

Example:

MESSAGE  'This produces short dump'   TYPE 'X'.

Output:
