the following example may be of some help to you:

DATA: lf_repid LIKE sy-repid, 
lf_dynnr LIKE sy-dynnr, 
lf_dynprofield LIKE help_info-dynprofld,
lf_retfield LIKE dfies-fieldname. 

MOVE sy-repid TO lf_repid. 
MOVE sy-dynnr TO lf_dynnr. 
MOVE 'PA_DPROF' TO lf_dynprofield. 
MOVE 'PROFILNAME' TO lf_retfield. 

PERFORM prepare_gt_value_tab. 

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST' 
EXPORTING 
retfield = lf_retfield 
dynpprog = lf_repid 
dynpnr = lf_dynnr 
dynprofield = lf_dynprofield 
value_org = 'S' 
TABLES 
value_tab = it_value_tab 
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.

Now to retrieve the selected field , 
READ TABLE it_value_tab INDEX 1 .
IF sy-subrc = 0 .
<field_to_get_Fvalue> = it_value_tab-fieldval .
ENDIF .
[code]

[/code]

Hi Prakash,

You can create a parameter instead of select-options and do it.. The FM for filling the search help with values is F4IF_FIELD_VALUE_REQUEST...

Call the FM in the event AT SELECTION-SCREEN ON VALUE REQUEST ...

After filling the values with search help, you can display the selected value by assigning the selected value to the parameter( In your case , the name is field)...

You can go through this link for more details..

http://www.sap-img.com/abap/value-request-for-parameter.htm

Close the thread once the problem is resolved.

Regards,

SP.
