at selection screen is when the screen is still in memory

then PBO happens

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.

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.
