Get data - Group by from inner query

Hi all,

I have the following query to select top 10 customers

SELECT top 10 A.Div as 'Div'

, A.CID as 'Customer_ID'

, A.CNAME as 'Customer_Name'

, B.REP as 'Primary_Rep'

,count(distinct B.SONO) as 'TY_Orders_Count'

, ISNULL(SUM(CASE A.SIVTYP_0

WHEN 'INV' THEN (B.QTY_0)

WHEN 'SCM' THEN (-B.QTY_0)

ELSE 0 END),0) as 'TY_Qty_UnitCount'

, ISNULL(SUM( D.PRICE *(CASE A.SIVTYP_0

WHEN 'INV' THEN (B.QTY_0)

WHEN 'SCM' THEN (-B.QTY_0)

ELSE 0 END)),0) as 'TY_COST'

from INVOICE_TABLE A

INNER JOIN INVDETAILS_TABLE B on A.IID = B.IID

INNER JOIN PRODUCTS_TABLE D on Year(B.INVDAT) = D.YEA_0 and D.PROD_ID = B.PROD_ID

where (B.INVDAT between '04/10/2015' AND '04/17/2015')

AND A.Div in ('AS','DF','GH','JH','KL')

group by

A.Div

,A.CID

,A.CNAME

,B.REP

This query returns top 10 customers in whole data. NOw I want to get top 10 customers for each division seperately

i.e top 10 customers in 'AS',top 10 customers in 'DF',top 10 customers in 'GH',top 10 customers in 'JH',top 10 customers in 'KL'

I tried with this query, but unable to get data for eac division

can anyone help me to do this

Thanks in advance
