MPP Action Events

When ever acction is performed on Screen raises PAI event and We can handle where action events related Code Functionality.

PBO ( Process Before Output )

This event is similer to Initialization of Selection-Screen.

This event used In mpp to Add Title Bar,

Menu Bar for the screen. Default Properties of the screen can be loaded.

This event is fired when Screen is Loading for the first Time, and when ever action is Perfomed on the screen.

When ever PAI is called , the event reloads the screen, hence PBO will be called automatically.

IF the select statement is used in PBO, see that statement is declared in a conditional statement. Else the statement is executed for number of times when ever we load the screen and action is performed.

example code:

1) Top include file.

data : okcode like sy-ucomm,

a type i.

2) PBO and PAI code.

MODULE STATUS_0101 OUTPUT.

if a = 0.

MESSAGE S000(ZMSGCLS).

a = 1.

endif.

ENDMODULE.

MODULE USER_COMMAND_0101 INPUT.

CASE OKCODE.

WHEN 'RAISE'.

WHEN 'EXIT'.

LEAVE PROGRAM.

ENDCASE.
