Clinging to Access 2003...
I have 2 versions of this 'sorta' working...

SELECT qryGroupedQuantities.strMaterial, qryGroupedQuantities.strSoldToPartyNum, qryGroupedQuantities.strSoldToPartyName, qryGroupedQuantities.SumOfCalcQuantity, (SELECT Count(*) AS HowMany
FROM qryGroupedQuantities AS Dupe
WHERE Dupe.strMaterial = qryGroupedQuantities.strMaterial
and (Dupe.SumOfCalcQuantity > qryGroupedQuantities.SumOfCalcQuantity
or(Dupe.SumOfCalcQuantity = qryGroupedQuantities.SumOfCalcQuantity and Dupe.id > qryGroupedQuantities.id))
) AS BeatenBy
FROM qryGroupedQuantities
ORDER BY qryGroupedQuantities.strMaterial, qryGroupedQuantities.SumOfCalcQuantity DESC;

gives perfect results - but takes hours to run (over 5 last time). Searching here at TT showed me the following (by PHV I believe in answer to a similar dilemma):

SELECT A.Date, A.Total, A.Type, 1+Count(B.Date) AS Rank
FROM qryTotal AS A LEFT JOIN qryTotal AS B ON A.Total<B.Total AND A.Date=B.Date
GROUP BY A.Date, A.Total, A.Type

That got me going in the right direction - so now I'm trying:

select qrygroupedquantities.strmaterial,qrygroupedquantities.strsoldtopartynum, qrygroupedquantities.strsoldtopartyname, qrygroupedquantities.sumofcalcquantity, Count(*)+1 as HowMany
from qrygroupedquantities left join qrygroupedquantities as Dupe on
Dupe.strMaterial = qryGroupedQuantities.strMaterial and (Dupe.SumOfCalcQuantity > qryGroupedQuantities.SumOfCalcQuantity or(Dupe.SumOfCalcQuantity = qryGroupedQuantities.SumOfCalcQuantity and Dupe.id > qryGroupedQuantities.id))
group BY qrygroupedquantities.strmaterial,qrygroupedquantities.strsoldtopartynum, qrygroupedquantities.strsoldtopartyname, qrygroupedquantities.sumofcalcquantity;

This runs in just a few minutes! The only issue is that for each strMaterial, the top and second ranked records both come up as 2 rather than 1 then 2.

Any suggestions? It's frustrating to be this close and not be able to see the way! Thanks in advance!

Aren't the quantities the same? If they are the same and you don't want them both to be 2 then you will need to define which should be 1 and which should be 2.

Replace Count(*) with Count(Dupe.strMaterial)

Hope This Helps, PH.

You'd think that was the case, but it appears that the

or(Dupe.SumOfCalcQuantity = qryGroupedQuantities.SumOfCalcQuantity and Dupe.id > qryGroupedQuantities.id)

is doing it's job EXCEPT where it involves the top 2 records. ex:
strmaterial strsoldtopartynum sumofcalcquantity HowMany
1080A[tab][tab]30323323[tab][tab]1080[tab][tab]2
1080A[tab][tab]30324100[tab][tab]50[tab][tab]2
1080A[tab][tab]3032A522[tab][tab]50[tab][tab]3

In keeping with this strange behavior, materials with only a single record are 'ranked' as 2 as well.

Again, replace this:
, Count([!]*[/!])+1 as HowMany
with this:
, Count([!]Dupe.strMaterial[/!])+1 as HowMany

Hope This Helps, PH.

Thank you both! PHV, I wasn't ignoring your initial posting of the fix, it must've gone through while I was getting my answer to dhookom together (in between dealing with work junk...)
