I have a view that I am works fine -

ALTER view [dbo].[_tec_SOP_POP_link] as
select SOP60100.SOPNUMBE as SOP_ORDER_NUMBER,
SOP60100.QTYRECVD as QtyReceivedSoFar,
SOP30200.sopnumbe as SOP_INV_NUMBER,
SOP60100.PONUMBER, SOP60100.QTYONPO as POQTY_REMAININGQTY,
POP10110.ITEMNMBR as ITEM_NUMBER,
POP10110.ITEMDESC as itemdescription, POP30310.UNITCOST as ReceivedCost,
Sum (case when pop30310.ponumber = sop60100.ponumber AND
pop30310.trxsorce like 'POIVC%' then pop30310.umqtyinb else 0 end) as TOTALINVOICEDMATCHED,
Sum (case when pop30310.ponumber = sop60100.ponumber AND
pop30310.trxsorce like 'POIVC%' then pop30310.extdcost else 0 end) as TOTALDOLLARSINVOICEDMATCHED,
from sop60100 inner join sop30200 on sop60100.sopnumbe = sop30200.ORIGNUMB AND sop30200.soptype = 3
inner join POP10110 on SOP60100.PONUMBER = POP10110.PONUMBER
inner join pop30310 on sop60100.ponumber = pop30310.ponumber
where SOP60100.ORD = POP10110.ORD
GROUP BY SOP60100.SOPNUMBE, SOP60100.QTYRECVD, SOP30200.sopnumbe, SOP60100.PONUMBER, SOP60100.QTYONPO,
POP10110.ITEMNMBR, POP10110.ITEMDESC, POP30310.UNITCOST, pop30310.umqtyinb

I want to add a column (UNITCOSTINVOICEDMATCHED)that divides TOTALDOLLARSINVOICEDMATCHED/TOTALINVOICEDMATCHED

I inserted the following (which did not work)-

Sum (TOTALDOLLARSINVOICEDMATCHED/TOTALINVOICEDMATCHED) as UNITCOSTINVOICEDMATCHED

error said - TOTALDOLLARSINVOICEDMATCHED column not recognized

The I inserted this statement - thinking I needed another case statement -

Sum(case when pop30310.ponumber = sop60100.ponumber AND
pop30310.trxsorce like 'POIVC%' then sum(pop30310.extdcost)/ sum(pop30310.umqtyinb)
else 0 end)as UNITCOSTINVOICEDMATCH

this returned the error -

Msg 130, Level 15, State 1, Procedure _tec_SOP_POP_link, Line 2
Cannot perform an aggregate function on an expression containing an aggregate or a subquery.

Any thoughts?

Thank you - it worked! (I had to remove the comma before the second from).

I have question though - what role/purpose of the lower case t at end on statement? I was curious - so I removed it and I got an error message - If i leave it it works fine.

Sorry to be so less knowledgeable - I do not work with transact sql enough to master it - my role is primarily teaching software application and not data reporting, etc....

I am totally impressed with the knowledge in this forum.

It is called alias. This is how you can refer to the columns in the derived table in outer query.
