It doesn't look like anything in my copy of Northwind (Access 2003).

I don't see where you specified a criteria. You need something like this at
the end:

WHERE ([Quantity Purchased]-[Quantity Sold]) > 0

Was this query showing the correct data (other than showing 0 where you
didn't want it)?

It northwind 2007 not 2003

even I specified a criteria as you told...it shows as below but still come
the same problem...


WHERE ((([Qty Purchased]-[Qty Sold])>0));

I try it in other field and it work as below
Qty Purchased: Nz([Quantity Purchased],0) , criteria >0
SQL show below:-


SELECT Products.ID AS [Product ID], Products.[Product Name], Products.
[Product Code], Nz([Quantity Purchased],0) AS [Qty Purchased], Nz([Quantity
Sold],0) AS [Qty Sold], Nz([Quantity On Hold],0) AS [Qty On Hold], [Qty
Purchased]-[Qty Sold] AS [Qty On Hand], [Qty Purchased]-[Qty Sold]-[Qty On
Hold] AS [Qty Available], Nz([Quantity On Order],0) AS [Qty On Order], Nz(
[Quantity On Back Order],0) AS [Qty On Back Order], Products.[Reorder Level],
Products.[Target Level], [Target Level]-[Current Level] AS [Qty Below Target
Level], [Qty Available]+[Qty On Order]-[Qty On Back Order] AS [Current Level],
IIf([Qty Below Target Level]>0,IIf([Qty Below Target Level]<[Minimum ReOrder
Quantity],[Minimum Reorder Quantity],[Qty Below Target Level]),0) AS [Qty To
Reorder]
FROM ((((Products LEFT JOIN [Inventory Sold] ON Products.ID = [Inventory Sold]
.[Product ID]) LEFT JOIN [Inventory Purchased] ON Products.ID = [Inventory
Purchased].[Product ID]) LEFT JOIN [Inventory On Hold] ON Products.ID =
[Inventory On Hold].[Product ID]) LEFT JOIN [Inventory On Order] ON Products.
ID = [Inventory On Order].[Product ID]) LEFT JOIN [Products On Back Order] ON
Products.ID = [Products On Back Order].[Product ID]
WHERE (((Nz([Quantity Purchased],0))>0));

When you see something with "AS" it means there is an alias for the field:

Nz([Quantity Purchased],0) AS [Qty Purchased]

[Qty Purchased] is the field name. [Qty Purchased] is the alias. For the
WHERE condition, try using the field name, as I suggested. I suggested you
try this:

WHERE ([Quantity Purchased]-[Quantity Sold]) > 0

but you did this:

WHERE ((([Qty Purchased]-[Qty Sold])>0))

Don't worry about the parentheses. Access throws those in there for reasons
that are not always clear. My point is that you are using the field name
aliases, but I think you need to use the actual field names.
