    SET @ANYDATE=GETDATE()

     SELECT TOP 20 DATePART(MONTH,@ANYDATE) [MONTH],
     DATePART(QUARTER,@ANYDATE) [Quarter], COUNT(1) [ACount]
     FROM ACTIVITY ACC
     INNER JOIN Accounts A ON ACC.Relatedtoid = A.ACCOUNTID
        AND ACC.OWNERID = A.OWNERID
     WHERE ACC.layoutid = 1015
        AND ACC.ownerid = 402
        AND A.LAYOUTID IN (
