Triggering event

[Former Member]

Hi All,

I have 4 drop down menus on a screen. I want to trigger an event as soon as the 1st drop down box is selected ..so that it can decide the what should be the input for next fields...

Thanks,

Sameer A M

hi first of all ur requirement is Dynamic read of the value selected in the first drop down in selection screen and then again dynamic updation of selection screen, kind of complex

Check this code which relates to the same stuff

• Vars for Dynamic Screen Population

DATA: PROGNAME TYPE SY-REPID,

DYNNUM TYPE SY-DYNNR,

DYNPRO_VALUES TYPE TABLE OF DYNPREAD,

FIELD_VALUE LIKE LINE OF DYNPRO_VALUES.

DATA: FLAG_END, FLAG_SEL, EXCH_SET, L_EXCH(3),ORD, ORDERSET.

DATA: RETURN TYPE TABLE OF DDSHRETVAL WITH HEADER LINE.

DATA: DYNFIELDS TYPE TABLE OF DYNPREAD WITH HEADER LINE.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR ST_NAME.

CLEAR: FIELD_VALUE, DYNPRO_VALUES.

REFRESH DYNPRO_VALUES.

FIELD_VALUE-FIELDNAME = 'EXCH'.

APPEND FIELD_VALUE TO DYNPRO_VALUES.

<b> CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

TABLES

DYNPFIELDS = DYNPRO_VALUES.</b> READ TABLE DYNPRO_VALUES INDEX 1 INTO FIELD_VALUE.

IF FIELD_VALUE-FIELDVALUE IS NOT INITIAL.

IF SY-SUBRC = 0 AND FIELD_VALUE-FIELDVALUE = 1.

FIELD_VALUE-FIELDVALUE = 'BSE'.

ELSEIF SY-SUBRC = 0 AND FIELD_VALUE-FIELDVALUE = 2.

FIELD_VALUE-FIELDVALUE = 'NSE'.

ENDIF.

SELECT STOCK ST_NAME
