Answer / saifur rahaman

you need to use FM 'DYNP_VALUES_READ' to read the screen
fields if you are not using OKCODE as ENTER.

For this functional module you need to pass passing the
program name, screen number and get the screen field vale
in dynpfileds table in the PROCESS ON VALUE-REQUEST.

see the sample code below.

PROCESS ON VALUE-REQUEST.
FIELD v_item MODULE f4help_item.
refresh it_dynpfields.
wa_dynpfields-fieldname = 'V_VBELN'.
append wa_dynpfields to it_dynpfields.
CALL FUNCTION 'DYNP_VALUES_READ'
EXPORTING dyname = sy-repid
dynumb = sy-dynnr
* TRANSLATE_TO_UPPER = ' '
* REQUEST = ' '
* PERFORM_CONVERSION_EXITS = ' '
* PERFORM_INPUT_CONVERSION = ' '
* DETERMINE_LOOP_INDEX = ' '
tables dynpfields = it_dynpfields.
* 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 .
IF sy-subrc 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

LOOP AT it_dynpfields into wa_dynpfields.

IF wa_dynpfields-fieldname = 'V_VBELN'.

V_VBELN = wa_dynpfields-fieldvalue.

ENDIF.
ENDLOOP.

IF NOT v_vbeln IS INITIAL.

SELECT vbeln posnr FROM vbrp INTO TABLE it_posnr WHERE
vbeln = v_vbeln.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
* DDIC_STRUCTURE = ' '
retfield = 'POSNR'
* PVALKEY = ' '
dynpprog = 'Z42778_F4_TEST'
dynpnr = '1000'
dynprofield = 'V_ITEM'
* STEPL = 0
* WINDOW_TITLE =
* VALUE = ' '
value_org = 'S'
* MULTIPLE_CHOICE = ' '
* DISPLAY = ' '
* CALLBACK_PROGRAM = ' '
* CALLBACK_FORM = ' '
* MARK_TAB =
* IMPORTING
* USER_RESET =
TABLES
value_tab = it_posnr.
* FIELD_TAB =
* RETURN_TAB =
* DYNPFLD_MAPPING = v_project
* EXCEPTIONS
* PARAMETER_ERROR = 1
* NO_VALUES_FOUND = 2
* OTHERS = 3

ENDIF.
