I am generating F4 help on selection screen using FM

F4IF_INT_TABLE_VALUE_REQUEST.

I want to display a message if there is no data to display in F4 help.

I tried and it is throwing dump on Sy-subrc value.

any help will not go unapprecaited.

Hi,

here is the Solution .

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            retfield    = 'CONNID'
            dynpprog    = progname
            dynpnr      = dynnum
            dynprofield = 'CONNECTION'
            value_org   = 'S'
       TABLES
            value_tab   = values_tab.

IF values_tab[] is initial.

Hi,

Before calling the FM check the value_tab internal table..

Example

<b> IF t_t005[] IS INITIAL.

MESSAGE S208(00) WITH 'NO values found'.

LEAVE SCREEN.

ENDIF.</b>

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = 'T005'

PVALKEY = ' '

retfield = 'LAND1'

dynpprog = sy-repid

DYNPNR = sy-dynnr

dynprofield = 'P_LAND1'

callback_program = sy-repid

value_org = 'S'

TABLES

value_tab = t_t005

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

Thanks,

Naren
