We can give F4 help to selection field or restrict the F4
help for specific values.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR so_vaplz-low.
SELECT werks arbpl ktext INTO TABLE it_vaplz FROM m_crama
CLIENT SPECIFIED
WHERE mandt = sy-
mandt
AND werks
= '4000'.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
retfield = c_vaplz
dynpprog = sy-repid
dynpnr = sy-dynnr
dynprofield = c_so_vaplz_low
value_org = 'S'
TABLES
value_tab = it_vaplz
* FIELD_TAB =
* RETURN_TAB =
* DYNPFLD_MAPPING =
EXCEPTIONS
parameter_error = 1
no_values_found = 2
OTHERS = 3
.
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV
Note --Validation is not possible with AT SELECTION-SCREEN
ON FIELD, Because it comes before entering the value in
selection screen.
AT SELECTION-SCREEN event comes in picture after entering
value in selection screen, so validation is possible only
here.
