sql server comma delimted string values into one row

I have a query that returns a row of multiple Itemcodes. The result is

   Date        group      list of item code
  2015-04-15    118       FYCT-00063,FYCM-00016,FYCM-00064,FYCF-00018

it’s working fine but i need the result like this, with quotes around every code 'FYCT-00063','FYCM-00016','FYCM-00064','FYCF-00018'

The query is this:

  SELECT DISTINCT SS.PostDate,SS.U_Unit,STUFF((
      SELECT ', ',+   CAST(OWOR.ItemCode AS VARCHAR(10)) [text()]
     FROM OWOR
     WHERE OWOR.PostDate=SS.PostDate AND OWOR.U_Unit=SS.U_Unit AND       OWOR.Status=SS.Status
  FOR XML PATH('') , TYPE)
  .value('.','NVARCHAR(MAX)'),1,2,' ') LISTGroup 
  from owor SS
  Where SS.PostDate='15.APRIL.15' AND SS.U_Unit='Unit No 2' and SS.Status!='C'

Answer

Try this

SELECT DISTINCT SS.PostDate
    ,SS.U_Unit
    ,STUFF((
            SELECT ', '
                + QUOTENAME(CAST(OWOR.ItemCode AS VARCHAR(10), ''''))
            FROM OWOR
            WHERE OWOR.PostDate = SS.PostDate
                AND OWOR.U_Unit = SS.U_Unit
                AND OWOR.STATUS = SS.STATUS
            FOR XML PATH('')
            ).value('.', 'NVARCHAR(MAX)'), 1, 2, ' ') LISTGroup
FROM owor SS
WHERE SS.PostDate = '15.APRIL.15'
    AND SS.U_Unit = 'Unit No 2'
    AND SS.STATUS != 'C'
