GT_LAND will not be filled by the system. You have to fill it before calling the F4 function module.

P079223,

There is not Append statement between the select and endselect, so there is no way that the values are appended to the table. So, you will have to insert APPEND statement.

Alternatively, if GT_LAND is of the same structure of T005T, you can use

select * from T005T into TABLE GT_LAND where spras = 'EN' and land1 = 'IN' and land1 = 'AU' .

The difference is the TABLE key word.

Ravi

Hi P079223,

Try this .

MODULE onvalue_land1 INPUT.

DATA : VALUE_TAB TYPE VRM_VALUES .

DATA WA LIKE LINE OF VALUE_TAB.

" First write the code to select values in int table

"GT_LAND

LOOP AT GT_LAND.

CLEAR WA.

MOVE Gt_LAND-LAND1 TO WA-KEY.

APPEAND WA TO VALUE_TAB.

ENDLOOP.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = 'P0002-NATIO'

VALUES = VALUE-TAB.

ENDMODULE.

( Also the list box on field P002-NATIO should be enabled in screen painter in SE51 . In the Text I/O Templates the dropdown cloumn should be set to "L" ).

Cheers

hi,

there retfield u have defined as 'NATI0' ( NATI ZERO). replace it with 'NATIO'(O for Oxford ).

after the function module according to ur requirement write the following code.

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 gt-return INDEX 1.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'NATI0'

dynpprog = sy-repid

dynpnr = sy-dynnr

dynprofield = 'P0002-NATIO'

value_org = 'C'

tables

value_tab = GT_LAND

return_tab = gt_return

exceptions

parameter_error = 1

no_values_found = 2

others = 3.

I hope this will work.

If ur problem is solved rewards points and close the thread.

So you want the text and not the three caharcter key.

Just use

LOOP AT GT_LAND.

CLEAR WA.

MOVE Gt_LAND-NATIO TO WA-KEY.

APPEAND WA TO VALUE_TAB.

ENDLOOP.

( Whatever you populate in KEY will be copied in screen field )

Else you can just read from internal table GT_PLANT in your porgram into another field.

Cheers.

What is your screen field ?? If its P0002-NATIO , it will take only 3 characters . If you want the full text then you define you screen field of type T005T-NATIO ( 40 chars). Check in SE11 both fields. You will find your answer.
