hi,

here is some info...........

If you created a search help in the DDIC...Then check the check box EXPORt parameter for one of the fields

If you used the function module Make sure you pass the correct values..Also the field name in CAPITAL letters..

Check this code..

TABLES: T005T.

DATA: BEGIN OF t_t005 OCCURS 0,

land1 TYPE t005-land1,

END OF t_t005.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 1(6) v_text FOR FIELD P_LAND1.

PARAMETERS: p_land1 TYPE t005-land1.

SELECTION-SCREEN COMMENT 13(35) v_text1.

SELECTION-SCREEN END OF LINE.

INITIALIZATION.

v_text = 'Country'.

v_text1 = ' '.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_land1.

REFRESH: t_t005.

SELECT land1

INTO TABLE t_t005

FROM t005.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = 'T005'

PVALKEY = ' '

retfield = 'LAND1'

dynpprog = sy-repid

DYNPNR = sy-dynnr

dynprofield = 'P_LAND1'

callback_program = sy-repid

value_org = 'S'

TABLES

value_tab = t_t005

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-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

other way would be..............

SELECT-OPTIONS: selcrit for <data>.

Now use

AT SELECTION-SCREEN ON VALUE-REQUEST FOR selcrit-LOW.

*Using the FM F4IF_INT_TABLE_VALUE_REQUEST to show the F4

AT SELECTION-SCREEN ON VALUE-REQUEST FOR selcrit-HIGH.*Using the FM F4IF_INT_TABLE_VALUE_REQUEST to show the F4

Hi,

First you create a serch help in the se11 t-code for that particular field.

Now assign that serch help with the syntax match code object beside the field.

press f1 for further help.

Use this piece of code

AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_belnr-HIGH .

Select all the required BELNR values into a table i_belnr to be displayed in the search help in the below form.

perform select.

perform help.

&----

*& Form help

&----

text

----

--> p1 text
<-- p2 text

----

form help.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

retfield = 'BELNR'

PVALKEY = ' '

dynpprog = sy-cprog

dynpnr = sy-dynnr

dynprofield = 'S_BELNR-LOW'

STEPL = 0
WINDOW_TITLE =
VALUE = ' '

VALUE_ORG = 'S'

MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '
MARK_TAB =
IMPORTING
USER_RESET =

tables

value_tab = i_belnr

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-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

pls go through this for search help creation

This is the Sample program for F4 help on Selection Screen.

REPORT zsel_f4help .

*---Report with selection screen and to display the list of

possible entries for field 'B' as per the value in field 'A'.

PARAMETERS: p_vbeln TYPE vbak-vbeln,

p_posnr TYPE vbap-posnr.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_posnr.

DATA: BEGIN OF help_item OCCURS 0,

posnr TYPE vbap-posnr,

matnr TYPE vbap-matnr,

arktx TYPE vbap-arktx,

END OF help_item.

DATA: dynfields TYPE TABLE OF dynpread WITH HEADER LINE.

dynfields-fieldname = 'P_VBELN'.

APPEND dynfields.

**Read the Values of the SCREEN FIELDs

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = sy-cprog

dynumb = sy-dynnr

translate_to_upper = 'X'

TABLES

dynpfields = dynfields

EXCEPTIONS

invalid_abapworkarea = 1

invalid_dynprofield = 2

invalid_dynproname = 3

invalid_dynpronummer = 4

invalid_request = 5

no_fielddescription = 6

invalid_parameter = 7

undefind_error = 8

double_conversion = 9

stepl_not_found = 10

OTHERS = 11.

**Find out the Value of P_VBELN

READ TABLE dynfields WITH KEY fieldname = 'P_VBELN'.

p_vbeln = dynfields-fieldvalue.

**Convert the Value into internal format

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

input = p_vbeln

IMPORTING

output = p_vbeln.

**Fetch the correponding itemnos from VBAP

SELECT posnr matnr arktx INTO TABLE help_item

FROM vbap

WHERE vbeln = p_vbeln.

**Generate the F4 help with internal table values

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'POSNR'

dynprofield = 'P_POSNR'

dynpprog = sy-cprog
