Drop Down in Selection Screen?

[Former Member]

Hi Experts,

I need to define a Parameter in Selection Screen, like,

P_Finanacila_Year---->shuld hv-->Drop Down peroperty(actually, once I did it by assigning the corresponding field of table to the Selection Screen filed, but now, I forget the Navigation),

So,

How to achieve it(Navigation)?

ThanQ.

hi Srinivas ,

i guess u mean to difine the parameter like a dropdown list whcih you can only get the

value from the list never input , so if that just define the parameter as listbox and that would be fine

Hi,

Is it a selction-screen OR a screen you create with SE51 ( screen painter ) because the solution is different in both case.

<b>[1]. Drop-down for Selection-Screen.</b>

PARAMETERS: p_augru LIKE vbak-augru VISIBLE LENGTH 10 AS LISTBOX.

This will show order reason values as Drop-down on selection screen. You can use addition <b>VISIBLE LENGTH n AS LISTBOX</b> with any "parameter" you want.

<b>[2]. Drop-down for screen variable created using SE51.</b>

- Display the screen layout using screen painter.

- Switch to change mode

- Double-click the variable you are insterested in having list-box.

- The "field attribute" screen will open.

- On this screen there is a <b>field called "Dropdown".</b> In this field <b>select 'listbox'</b> option.

- Also, if required set the visible length ( Vis. length) field with appropriate length so when the listbox is display, it has enough length to show description.

Let me know if you have any question.

ThanQ to all.

Hi RS,

Its Selection Screen, so I used ur first syntax i.e.

<i><b>PARAMETERS: p_augru LIKE vbak-augru VISIBLE LENGTH 10 AS LISTBOX</b></i>

Here(in ur example), I am getting the List Values, when I drop it down the p_augru field!

But, in my case, I am not getting the values i.e. Years. I defined like,

PARAMETERS p_gjahr LIKE bsad-gjahr VISIBLE LENGTH 4 AS LISTBOX.

May I know the reason?

ThanQ.

Hi,

Use the following code:

Decalration on the selection screen:

parameters: p_finyr(4) AS LISTBOX VISIBLE LENGTH 10 DEFAULT '2007'.

AT SELECTION-SCREEN OUTPUT.

PERFORM fill_listbox_p_finyr.

&----

---

*& Form fill_listbox_p_finyr

&----

---

• text

----

---

Form fill_listbox_p_finyr.

DATA: lt_list TYPE vrm_values,

ls_value LIKE LINE OF lt_list.

REFRESH: lt_list.

CLEAR: ls_value,

lt_list.

ls_value-key = '2007'.

ls_value-text = '- Current'.

APPEND ls_value TO lt_list.

ls_value-key = '2006'.

ls_value-text = '- Previous'.

APPEND ls_value TO lt_list.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'P_FINYR'

values = lt_list.

ENDFORM. " fill_listbox_p_finyr

Hi Nilesh,

OK, fine.

1- But, I need to display from 1990 till current year, so I need to mention every yaer in the Prog. as u mentioned as 2006 and 2007?

2- We(SAP) dont hv any easy solution(ready-made) for this i.e. Drop Down for Years?

(Actually, once I did by selecting the field in the corresponding table, but now I forget it the naviation!)

Looking for ur thoughts,

Anyways, ThanQ.
