Little bit of help

Question

Hi,
I wonder if anyone can help me with my problem.
Here is my piece of SQL.
I know what I currently have - *(CASE WHEN ITL.FROM_LOC_ID = 'W%' THEN 'D1' OR WHEN ITL.FROM_LOC_ID != 'W%' THEN 'D2' END) Site* is wrong.
And I was just wondering if anyone could show me how to set out what i'm trying to do in the correct way.
Basically, all I want is an extra column called 'Site' and if ITL.FROM_LOC_ID = 'W%' then display 'D1' if not then display 'D2'.
SELECT DISTINCT AU.NAME, ITL.REFERENCE_ID, (CASE WHEN ITL.FROM_LOC_ID = 'W%' THEN 'D1' OR WHEN ITL.FROM_LOC_ID != 'W%' THEN 'D2' END) Site
FROM INVENTORY_TRANSACTION ITL, ORDER_HEADER OH, APPLICATION_USER AU
WHERE CODE = 'Pick'
AND TO_LOC_ID = 'CONTAINER'
AND ITL.REFERENCE_ID = OH.ORDER_ID
AND OH.DELIVER_BY_DATE >= TO_DATE($P{Deliver_By_Date},'DD-Mon-YYYY')
AND OH.DELIVER_BY_DATE < TO_DATE($P{Deliver_By_Date},'DD-Mon-YYYY') + 1
AND ITL.USER_ID = AU.USER_ID
ORDER BY ITL.REFERENCE_IDThanks in advance.

Thanks Ibrahim,
I got some data back, adding that to my query. However I have just realised there may be something else I need to add in..
With adding that to my query each record displayed D2 in the Site column.
This is because my live data thats i'm pulling from the database looks like this;
Reference ID      Name               From_Loc_Id
0080107253        Sam Mardell        W0001
0080107253        Sam Mardell        W0003 
0080107253        Sam Mardell        W0004 
0080107253        Sam Mardell        W0005 
0080107253        Sam Mardell        W0008
0080107253        Dan Smith          A07A 
0080107253        Dan Smith          A45A
0080107253        Dan Smith          B37A
0080107253        Dan Smith          D34A
0080107253        Dan Smith          E02A   So my output I would like to look like this;
Reference ID      Name               Site
0080107253        Sam Mardell        D1
0080107253        Dan Smith          D2  Currently i'm getting;
Reference ID      Name               Site
0080107253        Sam Mardell        D2
0080107253        Dan Smith          D2  I think because the Reference_ID refers to both sites in the query.
Hope this makes sense.
SM.
