F4 Help

Former Member — Tue, 21 Nov 2006 11:48:59 GMT

Hello all,

I have a report program. What I want is that when the user presses F4 for a particular selection screen parameter, a list of values should be displayed. This list is taken from a table skb1.

One concern is that all entries should not be displayed. Only those entries which specify a certain criterion ( eg. a field should be 'X' in the db table ) should be displayed.

Hi ravi,

1. sample code (just copy paste)

REPORT ABC.

*----

DATA : BEGIN OF ITAB OCCURS 0,

UNAME LIKE USR01-BNAME,

END OF ITAB.

data : RETURN_TAB LIKE DDSHRETVAL occurs 0 .

data : RETURN_wa LIKE DDSHRETVAL .

*----

PARAMETERS : A(12) TYPE C.

*----

AT SELECTION-SCREEN ON VALUE-REQUEST FOR A.

ITAB-UNAME = 'U01'. APPEND ITAB.

ITAB-UNAME = 'U02'. APPEND ITAB.

ITAB-UNAME = 'U03'. APPEND ITAB.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

retfield = 'ITAB-UNAME'

PVALKEY = ' '

DYNPPROG = SY-REPID

DYNPNR = SY-DYNNR

DYNPROFIELD = 'A'

STEPL = 0
WINDOW_TITLE =
VALUE = ' '

VALUE_ORG = 'S'

MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '
MARK_TAB =

USER_RESET =

tables

value_tab = ITAB

FIELD_TAB = FTAB

RETURN_TAB = return_tab

DYNPFLD_MAPPING =
EXCEPTIONS
PARAMETER_ERROR = 1
NO_VALUES_FOUND = 2
OTHERS = 3

break-point.

hi,

in order to display only the selected entries you have to create a matchcode object and match code id in SE11 and asssign to parameter or select option.
