It can sometimes be useful to issue (create) system messages from an ABAP program rather than interactively. For example, you can issue warning messages from a background job before starting a database backup or other action that causes the system to pause.
To issue a message under program control, you need to create a program that calls the function module shown below. When the program runs (for example, as a job step in a background job), the message that you specify is displayed immediately as a system message. The message expires and is no longer displayed at the time that you specify.
Syntax
data: emtext like TEMSG-EMTEXT. data: exp_time like TEMSG-TIMDEL. emtext = "Bitte abmelden. Backup in 2 Minuten. exp_time = '230000'. CALL FUNCTION 'SM02_ADD_MESSAGE' EXPORTING MESSAGE = emtext " 1. line of the message MESSAGE2 = " 2. line MESSAGE3 = " 3. line SERVERNAME = " Server EXPIRATION_DATE = SY-DATUM " Expiration date with EXPIRATION_TIME = '230000' " time DELETE_DATE = ' ' " Deletion date with DELETE_TIME = '230000' " time CLIENT = ' ' " Client IMPORTING MESSAGE_ID = EXCEPTIONS EMPTY_MESSAGE = 1 SERVER_NOT_AVAILABLE = 2 CLIENT_NOT_AVAILABLE = 3 NOT_AUTHORIZED = 4 OTHERS = 5
Note
As you can see in the example program, messages have the same format as in the dialog transaction: A maximum of three lines each with a maximum of 60 characters. Only the first line has to be filled.
Use 12 or 24 hour format as set in the user master record under which the program will run. If only time is specified, today’s date is assumed.
Always enter a time.
Each time your program runs, the message you specify is issued to all users.
