Hi,

You need to construct the F4 help in the event block

AT SELECTION-SCREEN ON VALUE-REQUEST FOR.

Here use this FM F4IF_INT_TABLE_VALUE_REQUEST to construct the F4 help.

Please see the below code is the best example of passing the table values as F4 help values in the selection screen through the even of the report .....

REPORT Ztest_HELP .
TABLES : MARA.
SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.
PARAMETERS : P_MATNR(10) TYPE C.
SELECTION-SCREEN END OF BLOCK B1.
DATA : BEGIN OF ITAB OCCURS 0,
MATNR TYPE MATNR,
END OF ITAB.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_MATNR.
SELECT MATNR
FROM MARA
INTO TABLE ITAB
UP TO 10 ROWS.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
RETFIELD = 'MATERIAL NUMBER'
DYNPPROG = SY-REPID
DYNPNR = SY-DYNNR
DYNPROFIELD = 'P_MATNR'
VALUE_ORG = 'S'
TABLES
VALUE_TAB = ITAB
EXCEPTIONS
PARAMETER_ERROR = 1
NO_VALUES_FOUND = 2
OTHERS = 3. 

<b>

There are number of function modules that can be used for the purpose, but these

can fullfill the task easily or combination of them.</b>

" DYNP_VALUE_READ
" F4IF_FIELD_VALUE_REQUEST
" F4IF_INT_TABLE_VALUE_REQUEST
" POPUP_WITH_TABLE_DISPLAY
" DYNP_VALUE_READ  

This function module is used to read values in the screen fields. Use of this

FM causes forced transfer of data from screen fields to ABAP fields.

There are 3 exporting parameters

DYNAME = program name = SY-CPROG

DYNUMB = Screen number = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

and one importing TABLE parameter

DYNPFIELDS = Table of TYPE DYNPREAD

The DYNPFIELDS parameter is used to pass internal table of type DYNPREAD

to this FM and the values read from the screen will be stored in this table.This

table consists of two fields:

FIELDNAME : Used to pass the name of screen field for which the value is to

be read.

FIELDVALUE : Used to read the value of the field in the screen.

reward points if it is usefull ...

U can also directly assign search help to the screen element using 'match code ' option

select-options:select-options: s_ihrez for vbak-ihrez matchcode object '.......'(search help name)

steps:

Step1: Execute transaction SE11

Step2: Create new search help called 'ZSH' (must be less than 5 chars long to be used as matchcode)

Step3: Enter the following details:

Step4: Save and activate

Step5: Add following line into your program: PARAMETER p_prog LIKE trdir-name MATCHCODE OBJECT zsh.

Or see other methods of adding a search help.
