Former Member — Wed, 28 Apr 2010 15:25:28 GMT

Hi all,

Im using ''VRM_SET_VALUES'' FM to populate values for listbox in the 'At selection-screen output' event.

I want to know how to find the value which the user selects in the list box.

Pls tell me how to achieve the same.

Hi,


 CALL FUNCTION 'VRM_SET_VALUES'
  EXPORTING
    id              = 's_list'

The value is what is in variable "s_list" at the moment.

You should be using it in the AT SELECTION-SCREEN ON VALUE REQUEST event.

Hi,

VRM_GET_VALUES will return you the values that is set by the user. The selected value will be in an internal table and you need to read the 1st Index. Have a look at the code below.


data: delimiter type c value '/'.
TYPE-POOLS VRM.
data: VRM_ID TYPE VRM_VALUE-TEXT,
VRM_VALUES TYPE VRM_VALUEs with header line.

vrm_id = 'PO_INFO'.

CALL FUNCTION 'VRM_GET_VALUES'
EXPORTING
ID = vrm_id
IMPORTING
VALUES = vrm_values[]
EXCEPTIONS
ID_NOT_FOUND = 1
OTHERS = 2.

read table vrm_values index 1.

po_info = vrm_values-key.

The above code will return you all the values for a particular Screen element. You can use the below code snippet to retrieve the value selected by the User.



  DATA: lc_dyname    LIKE sy-repid.
  DATA: lc_dynumb    LIKE sy-dynnr.
  DATA: ltab_fields  LIKE dynpread OCCURS 0 WITH HEADER LINE.
    ltab_fields-fieldname = 'TB_01'.
  APPEND ltab_fields.

CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      dyname     = lc_dyname
      dynumb     = lc_dynumb
    TABLES
      dynpfields = ltab_fields
    EXCEPTIONS
      OTHERS     = 01.

The above code snippet will retrieve the particular row information in your PAI event for processing.

Hope this code snippet will help you.

Thanks,

Samantak.

Hi shanthi,

PARAMETERS:po_list TYPE name1 AS LISTBOX VISIBLE LENGTH 20

DEFAULT 'OPTION1' OBLIGATORY.

AT SELECTION-SCREEN OUTPUT.

TYPE-POOLS: vrm .

DATA:

l_name TYPE vrm_id,

li_list TYPE vrm_values,

lwa_list LIKE LINE OF li_list.

l_name = 'PO_LIST'.

CLEAR lwa_list.

REFRESH li_list.

lwa_list-text = lwa_list-key = 'OPTION1'.

APPEND lwa_list TO li_list.

CLEAR lwa_list.

lwa_list-text = lwa_list-key = 'OPTION2'.

APPEND lwa_list TO li_list.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = l_name

values = li_list.

Output will have OPTION1 and OPTION2 in the listbox.

If OPTION1 is selected in the selection screen then po_list will have value as 'OPTION1'

If OPTION2 is selected in the selection screen then po_list will have value as 'OPTION2'

Hope this will help.
