what is the difference between AT SELECTION-SCREEN and AT SELECTION-SCREEN-OUTPUT.

PBO + AT SELECTION SCREEN = AT SELECTION SCREEN OUTPUT?

like based on 1st screen validations 2nd screen has to enable or disable.

Hello

AT SELECTION-SCREEN-OUTPUT = <b>PBO</b> before sending the selection screen

AT SELECTION SCREEN = <b>PAI</b> after user entered ENTER or executes report

at selection screen is when the screen is still in memory

then PBO happens

then At selection screen on output is after the screen is displayed

AT SELECTION_SCREEN OUTPUT is executed at the PBO of the selection screen after the user presses ENTER key.

In this one can LOOP AT SCREEN and modify the screen properties.

This simple program says all..

TABLES: MKPF.

DATA: ITAB LIKE STANDARD TABLE OF MSEG.

PARAMETERS: P_MBLNR LIKE MKPF-MBLNR,

P_DATE LIKE MKPF-CPUDT.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF SCREEN-NAME EQ 'P_MBLNR'.

SCREEN-REQUIRED = 1.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

AT SELECTION-SCREEN.

SELECT SINGLE * FROM MKPF WHERE MBLNR EQ P_MBLNR.

IF SY-SUBRC NE 0.

MESSAGE 'Not exists' TYPE 'E'.

ENDIF.
