how to disply error messages if values not available fpr F4 help

[Former Member]

Hi,

I have implemented F4 help for a selection screen field using function module.

I want to throw a customized error message if no value is available.

In my case if no value is available it gives standard message no value available.

I have tried but it gives a dump.

Please suggest.

Thanks and Regards

for F4 help defenitely you will be having a select query to populate into internal table

if it is so

after the select query with sy-subrc check

if yes

then it will proceed with the function module

if no then throw error message

message

use this code

form f_f4help .
  data : begin of it_itab occurs 1,
           username type usr02-bname,
           end of it_itab.

  select bname from usr02 into table it_itab.
if sy-subrc = 0

  call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
      retfield        = 'BNAME'
      dynpprog        = sy-repid
      dynpnr          = sy-dynnr
      dynprofield     = 'P_USER'
      value_org       = 'S'
    tables
      value_tab       = it_itab[]
    exceptions
      parameter_error = 1
      no_values_found = 2
      others          = 3.
  if sy-subrc  ne 0.
*   MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  endif.
else.
message with error.
endif.
endform.

hi,

if you have used FM 'F4IF_INT_TABLE_VALUE_REQUEST' to display f4.

then before calling this fm check if the data table u r passing is initial or not.

if that is initail through your msg instead of calling FM.

Hi Shradhha,

If you are using 'F4IF_INT_TABLE_VALUE_REQUEST' function module for F4 help then after calling the FM check for sy-subrc. If sy-subrc = 2 then give your message there as the FM returns 2 when no values found. Hope this will solve your problem.

           END OF it_itab.

  SELECT matnr
         meins FROM mara INTO TABLE it_itab UP TO 10 ROWS.

  IF it_itab[] IS NOT INITIAL.
    CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

        retfield        = 'MATNR'
        dynpprog        = sy-repid
        dynpnr          = sy-dynnr
