Hi,

Are you reading the table RETURN_TAB of this function module after calling it. The value selected is returned in this table.

Regards,

Jayesh

Hi, <li>Are you passing values to FM like below


  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield    = 'IWERK'  "it_t399i table field.
      dynpprog    = sy-repid
      dynpnr      = sy-dynnr
      dynprofield = 'P_SWERK' "Screen field on which values is placed.
      value_org   = 'S'
    TABLES
      value_tab   = it_t399i
      return_tab  = it_return_tab.

<li>You do not need to read return_tab to place value when you double click. Thanks Venkat.O

Hi,

The selected values will be returned in RETURN_TAB after that call FM to display data on input field.

IT_DYNP_LIST should be filled with the selected value from F4 help FM.

Fetch the selected value

read table it_retvals into wa_retvals index 1.

wa_dynp_list-fieldname = c_field1 . "FIELD name.

wa_dynp_list-fieldvalue = wa_retvals-fieldval..

append wa_dynp_list to IT_DYNP_LIST.

clear : wa_dynp_list.

Use FM to display data on input field

call function 'DYNP_VALUES_UPDATE'

exporting

dyname = sy-repid

dynumb = sy-dynnr

tables

dynpfields = it_dynp_list.

Hope this may be helpful.

Thanks,

Sravanthi.V

In the export parameter Retfield, you need to specify the field of the internal table whose value is to be returned to the return tab.

After calling the FM, read return_tab and pass the value to the screen field.

i've tried this

EXPORTING

retfield = 'customer_no' this is the table field

dynpprog = sy-repid

dynpnr = sy-dynnr

dynprofield = 'F2' this is the field in the screen that the value ( customer_no) should appear in it

value_org = 'S'

TABLES

value_tab = G_TAB_CON_ITAB this is my internat table

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

return_tab>>> bring me a runtime error

note: when i didn't use the return_tab and execute my program and select from the list, the I/O field (F2) shows a random value from the same record i select but not the ( customer_no) which i want it to be displayed.

I wrote the following code which worked fine. The screen field is p_pernr and customer no is replace with personal number here.

PARAMETERS: P_PERNR TYPE PERSNO.

Data: Itab type standard table of p0001,

RETURN_TAB TYPE STANDARD TABLE OF DDSHRETVAL WITH HEADER LINE.

At selection-screen on value-request FOR P_PERNR.

Select * from pa0001 into corresponding fields of table itab up to 50 rows.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

RETFIELD = 'PERNR'

PVALKEY = ' '
DYNPPROG = ' '
DYNPNR = ' '
DYNPROFIELD = ' '
STEPL = 0
WINDOW_TITLE =
VALUE = ' '

VALUE_ORG = 'S'

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

TABLES

VALUE_TAB = ITAB

FIELD_TAB =

RETURN_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.

ELSE.

READ TABLE RETURN_TAB INDEX 1.

P_PERNR = RETURN_TAB-FIELDVAL.

ENDIF.
