Listbox default value.

[Former Member]

Hello,

i have generated a dropdown list using the VRM_SET_VALUES FM, but i can"t set the default value to this list.

here is a sample of my code :

SELECT  pos value
  FROM zfee_scr_param
  INTO TABLE list
  WHERE fieldname = 'CDL'.
  SORT list BY key.
  name = 'ADRSTREET-ZZ_CONTR_LOC'.
  CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING
      id     = name
      values = list.

Thank you,

Tom.

hI,

try liek this

for example.

PARAMETER: pr_spart TYPE spart AS LISTBOX VISIBLE LENGTH 7 default 'HL'.

'HL' is one of the value that is there in the list box.

Hi Tom,

on initialization event, just give the key value (be sure to give the key value) to the listbox parameter.

example:

***

TYPE-POOLS : vrm.

DATA: combo_id TYPE vrm_id,

items TYPE vrm_values WITH HEADER LINE,

item TYPE LINE OF vrm_values.

***

selection-secreen begin of block b1.

PARAMETERS: pp1(20) AS LISTBOX VISIBLE LENGTH 30.

selection-screen end of block b1.

***

• for your example

loop at list.

item-key = list-pos.

item-text = list-value.

APPEND item TO items. CLEAR item.

endloop.

*

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'PP1'

values = items[]

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

***

on initialization.

pp1 = <your default value>.

it gets the initial value..

Thanks,

i thought this was the answer to my question, but as i don't have a dropdown declared as a parameter but created via screen painter, i can't do it this way.

SELECT pos value

FROM zfee_scr_param

INTO TABLE list

WHERE fieldname = 'CDL'.

SORT list BY key.

name = 'ADRSTREET-ZZ_CONTR_LOC'. -> name of the dropdown as defined in screen painter

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = name

values = list.

Could there be a way to assign the key value to this dropdown ? could not find the syntax...

hi Tom,

as i understand your combo field is not on selection-screen but you can do the same on screen element as well. just create a PBO module and fill your internal table and listbox there.

example:

IN PBO MODULE

CLEAR : items,items[], item.

combo_id = 'GT_MAIN-REASON'.

item-key = '1'.

item-text = 'TOURISTIC'.

APPEND item TO items. CLEAR item.

item-key = '2'.

item-text = 'BUSINESS'.

APPEND item TO items. CLEAR item.

item-key = '3'.

item-text = 'EDUCATION'.

APPEND item TO items. CLEAR item.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = combo_id

values = items[]

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

READ TABLE items WITH KEY key = gt_main-reason.

gt_main-reason_tx = items-text.

• this fills your listbox on the screen (change the names accordingly)

IF gt_main-reason IS INITIAL.

gt_main-reason = '1'.

ENDIF.

• this part looks if the field is empty and gives the initial value 'TOURISTIC' (key value is 1 for TOURISTIC)

no need to take points back

Hi Murat!

First of all: Thanks 4 your answers which made me find this topic

Unfortunately your coding does not set the value to 'TOURISTIC' (key value is 1 for TOURISTIC), but to 1.

Any help of how i could select a certain list entry instead of setting the value 1?

Cheers & Thx in advance

Hi Jan,

i just saw your reply by chance, i wasn't watching this thread.

this is a working code, it sets the selection to "Touristic" when set to "1". is it possible that you may have given key values with different data type or value so it can not realize matching value? this case you have written happens when you give a value that is not in the combo box. can you double check?

Hi,

thx for your fast answer. i checked it in the debugger and made a screen:

http://www5.pic-upload.de/23.08.10/8132e7iepx1l.jpg

I also tried to change it to add '1' to... in the filling form for the listbox. it does not work. seems that abap does not match my G_0300-ddlifnr = 1. (or = '1') to my first entry. Dont know why

g_dd_lb_value_key TYPE i. --> so imho it has to work without the ''....

Maybe i have to try another key for my table, but i need one which i can increase in a loop, cause of not knowing how many values i'll have in my listbox.

kind regards!
