Hi,

I have created a Z-Function module..where 1 pop-up will come and while pressing F4 it will go to

process on value-request..and it is working fine in SE37

But when i am using in my program..same FM with same parameter ...the F4 button is not working ...control is not going to processon value-request

Hi,

You cannot get the F4 Pop-Up for FM in the Program, beacuse for this F4 need's to be handled in the Program.

hi priya,

call the FM under event AT selection-screen on value request for <fname>;

i think then it will trigger.

Hi Priya,

As you says there is no problem with your function module,so it should work if you r using that

customize function module.

There is standard function module for F4 help ,you can use that one,is there any reason for creating

cust FM.

Use in this way

FORM sub_f4_help .

• Selecting plant for f4 help for palnt in selection screen

SELECT werks "Plant

name1 "Name

FROM t001w

INTO TABLE it_werks

WHERE werks IN (g_w1,g_w2,g_w3).

IF sy-subrc = 0.

SORT it_werks.

ENDIF.

• FM used to populate plant(2000,5000,6000) in f4 help

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'WERKS'

pvalkey = ' '

dynprofield = 'S_WERKS-LOW'

value_org = g_kind

TABLES

value_tab = it_werks "Fields of the hit list

return_tab = it_return "Return selected value

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc = 0.

READ TABLE it_return INTO wa_return INDEX 1.

IF sy-subrc = 0.

s_werks-low = wa_return-fieldval.

ENDIF.

CLEAR : it_return[],

wa_return.

ENDIF.
