Hi Amit..

Before u write the post,Plz check existing solution posted by our SCN members..

comes to question..

in Screen painter you have to mention that field as listbox.

and in PBO u have to fill the list box(key and value by using your custom code..)

Example:

MODULE fill_carrid OUTPUT.
* Do not use this process (but it works)

   TYPE-POOLS vrm.
   DATA values TYPE vrm_values WITH HEADER LINE.

   IF init is initial.
     SELECT * FROM scarr.
       values-text = scarr-carrname.
       values-key = scarr-carrid.
       APPEND values.
     ENDSELECT.
     CALL FUNCTION 'VRM_SET_VALUES'
          EXPORTING
               id              = 'SBOOK-CARRID'
               values          = values[]
          EXCEPTIONS
               id_illegal_name = 1
               OTHERS          = 2.
     IF sy-subrc <> 0.
       MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
               WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
     ENDIF.

   ENDIF.
   scarr-carrid = 'LH'.
   init = 'X'.
ENDMODULE.                             " FILL_CARRID  OUTPUT

in sap standard Module pool program is there,name: rsdemo_dropdown_listbox

Amit,

data: GV_CHARGE.

In screen painter GV_CHARGE as dropdown with FCODE:<ACT>

In PBO

TYPE-POOLS vrm.
   DATA values TYPE vrm_values WITH HEADER LINE.

       values-text = 'Freight Charges'.
       values-key = '1.
       APPEND values.

       values-text = 'Air charges'.
       values-key = '2'.
       APPEND values.

       values-text = 'TMS Charges'.
       values-key = '3'.
       APPEND values.

CALL FUNCTION 'VRM_SET_VALUES'
          EXPORTING
               id              = 'GV_CHARGE'
               values          = values[]
          EXCEPTIONS
               id_illegal_name = 1
               OTHERS          = 2.

In PAI

USERCOMMAND:

WHEN 'ACT'.

read values with key key = gv_charge.

if sy-subrc = 0.

if values-key = '2'.

amount = '20,000'.

endif.

endif.

Thank you,

Ravi.

Hi Ravi,

Thank u very much for ur help.

just one question. while searching other blogs i got 1  solution that we can make fixed value entries in Domain--->Value range.

What is the difference beween these 2.

Thanks,

yes Amit,

first..we can fill the drop down (key and text) in Module pool program/Report by using

1.SE11 - Dictionary(Domain level).

2.Manual filling in Program(fill internal table VALUES[] by using providing our key and text)(Program level).

3.Process on Value Request.(Program level).

Depending the user Requirement/Maintaining values  we have to decide..

i already mentioned earlier  Standard programs are in SAP regarding this listbox..

ex:rsdemo_dropdown_listbox

please check this program to learn more about listbox..

Thanks,

P.Ravi
