Drop down list in Module Pool

[Former Member]

Hi Friends,

I am trying to use drop down list in module pool program.

REFRESH v.

CLEAR vw.

vw-key = '1'.

vw-text = 'C Form Entry'.

APPEND vw TO v.

vw-key = '2'.

vw-text = 'C Form Display'.

APPEND vw TO v.

vw-key = '3'.

vw-text = 'C Form Update'.

APPEND vw TO v.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'C_FORM_MENU'

values = v

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

Using above program I can put value in list box in PBO.

But how can I know which value is selected by user in PAI.

Please guide me.

Thank you

Hi,

create a variable in your program with the name same as screen field name(list box field) then always the selected value will be present in that variable.

check values sy-subrc, sy-curow, sy-..... and so on.

Amit,

For example, consider you have function code 'SELECTED' for your dropdown list box.

MODULE user_command_9100 INPUT.

CASE ok_code.

WHEN 'BACK'. LEAVE TO SCREEN 0.

WHEN 'EXIT'. LEAVE TO SCREEN 0.

WHEN 'CANC'. LEAVE TO SCREEN 0.

WHEN 'SELECTED'.

READ TABLE v INTO wv BINARY SEARCH

WITH KEY key = C_FORM_MENU.

IF sy-subrc = 0.

MESSAGE i398(00) WITH 'Key: ' wv-key

'Value: ' wv-text.

ENDIF.

ENDCASE.

ENDMODULE. " USER_COMMAND_9100 INPUT

This will display a information box with the values you selected from the dropdown list box.

C_FORM_MENU variable will contain the value.

Hi,

This example will help you in retrieving values from list box.

DATA: g_name1  TYPE vrm_id,
      g_list1  TYPE vrm_values,
      g_wa_list LIKE LINE OF g_list1,
      g_value_1 LIKE LINE OF g_list1.

DATA: g_status(20) TYPE c.

CONSTANTS: c_status TYPE string VALUE 'G_STATUS',
                     c_to_be_sub TYPE string VALUE 'TO BE SUBMITTED',
                    c_sub TYPE string VALUE 'SUBMITTED',
                    c_chg_needed TYPE string VALUE 'CHANGE NEEDED',
                    c_app TYPE string VALUE 'APPROVED'.

In PBO we populate list box.

MODULE f4_scr OUTPUT.


  REFRESH g_list1.
  g_name1 = c_status.
  g_value_1-key = c_to_be_sub.
  g_value_1-text = c_to_be_sub.
  APPEND g_value_1 TO g_list1.

  g_value_1-key = c_sub.
  g_value_1-text = c_sub.
  APPEND g_value_1 TO g_list1.

  g_value_1-key = c_chg_needed.
  g_value_1-text = c_chg_needed.
  APPEND g_value_1 TO g_list1.

  g_value_1-key = c_app.
  g_value_1-text = c_app.
  APPEND g_value_1 TO g_list1.

  IF NOT g_list1 IS INITIAL.
    CALL FUNCTION 'VRM_SET_VALUES'
      EXPORTING
        id     = g_name1
        values = g_list1.
  ENDIF.

ENDMODULE.                 " F4_SCR  OUTPUT

*Function module to get the list box values. * we write this code in PAI

MODULE user_command_9000 INPUT.

 g_name1 = c_status.
  CALL FUNCTION 'VRM_GET_VALUES'
    EXPORTING
      id           = g_name1
    IMPORTING
      values       = g_list1
    EXCEPTIONS
      id_not_found = 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.

  READ TABLE g_list1 INTO g_wa_list WITH KEY key = g_status.
  IF sy-subrc EQ 0.
    g_status = g_wa_list-text.
  ENDIF.

ENDMODULE.

This will surely help to retrieve the values from list box.

Plz reward if useful.

Thanks,

Dhanashri.
