Restricting the systems items on the 'find system items' window

Question

I am trying to do some customizatiosn on form POXPOEPO. block PO_LINES and item_name is po_lines.item_number which is beside field 'Type' (line_type). when the three dots are pressed then a window appears to input 'enter reduction criteria for long list' when the percentage is pressed 'System Items' find window appears listing all the items defined. what i want this window to display only those items for which item_type = 'Consums' on MTL_system_items and 'user item type' on 'master item' definition window tab 'main'.
What is the way to achieve this.
i did like this but it is not working:
procedure event(event_name varchar2) is
form_name varchar2(30) := name_in('system.current_form');
block_name varchar2(30) := name_in('system.cursor_block');
item_name varchar2(60) := name_in('system.cursor_item');
begin
if (event_name = 'WHEN-NEW-ITEM-INSTANCE') then
     if (form_name='POXPOEPO') then
          if (block_name='PO_LINES') then
               if (item_name='PO_LINES.ITEM_NUMBER') then
                    FND_MESSAGE.SET_STRING('Iam here now');
                    fnd_message.show;
               fnd_key_flex.update_definition(
               BLOCK=>'PO_LINES',
               FIELD=>'ITEM', -- tried various things here like 'ITEM_NUMBER_MIR, PO_LINES.ITEM_NUMBER
               ENABLED=>'Y',
               WHERE_CLAUSE=>'item_typet = ''Consums'''
               end if;
               end if;
     end if;
else
null;
end if;
end event;
any guidance in this regard is appreciated.

Hi,
Please can you tell me How did you resolved this?
I want to modify the Item List as follows: show me all items on mtl_system_items_b where attribute10='Y'.
I did It:
IF( form_name = 'POXPOEPO' AND block_name = 'PO_LINES' and item_name='PO_LINES.ITEM_NUMBER') then
fnd_key_flex.update_definition( BLOCK=>'PO_LINES'
,FIELD=>'ITEM_NUMBER'
,ENABLED=>'Y'
,WHERE_CLAUSE=>'ATTRIBUTE10=''Y'' '
END IF;
But the list not show me all items where attribute10='Y'. I don't know why.
I see that list only show me the items where organization of master organization.
I would like to know: How to the standart forms define flexfield and where?. If i know it i guess i can show all items.
Thnks
