Access SQL IIf statement with GROUP BY (no alias utilized) (1 Viewer)

[rtsmith555]

I keep getting an error when I try to run this stating:

"Your query does not include the expression 'Iif([DEMAND Last 36 Mos]<3,0,[MAX Qty 3-Mo]-[Balance])' as part of an aggregate function."
I have included the expression under GROUP BY, however, so I'm at a loss.

I have added the expression to GROUP BY (not the alias) but the query won't recognize it. As far as I know, I'm still under the 10 field limit with GROUP BY.

Can anyone find my error?

Access SQL?
Even the entire FROM block with the JOINs does not correspond to the syntax required by Jet-SQL. It's never going to work that way.

Your aggregations are strange and deeply nested. It's confusing anyway and probably won't work that way.

How did you write this statement?

Agree with ebs. This is a Rube Goldberg set of queries. My gut tells me there's a much better way to get the information you need than this house of queries built on tables of suspect structure.

With that said, I think your error arises because you are trying to calculate a field and simutaneously use that calculated field:

SELECT
...
sum([NEW-ZTAC]![Open PO Q'ty ZE01]+[NEW-ZTAC]![Open PO Q'ty ZN01]) AS [Due In],
sum([NEW-ZTAC]![Open SO Q'ty]) AS [Due Out],
sum([NEW-ZTAC]![Not Allocated Q'ty]+[Due In]-[Due Out]) AS [Balance],
...

[Due In] and [Due Out] don't get their values until the query is run entirely. But the query can't run entirely until [Balance] is completed. But [Balance] can't be completed until [Due In] & [Due Out] are calculated. But [Due In] & [Due Out] don't get their values....etc. etc.

So (and I am not recommending this because I think you chosen the entirely wrong path already) is you would need to do the [Due In] & [Due Out] caluclations in a query then build another query using it so you can calculate [Balance].

In my experience a field called [Balance] should not be calculated by adding various fields together. Instead it should be calculated by using SUM() on just one field. Think of a bank account. You would have a tblTransactions that looks like this:

tblTransactions
trans_Date, trans_Note, trans_Amount
1/1/2023, Work Check Deposit, 1100
2/2/2023, Rent, -600
3/3/2023, Groceries, -100
4/4/2023, Tax Refund, 200

Now, when I want that balance I run this query:

SELECT SUM(trans_Amount) As Balance FROM tblTransactions

That's it, I simply sum the trans_Amount field and get my balance. I don't need to add a bunch of fields togther.

I think you have a fundamental error in your tables if you need to add so many fields together and requring so many queries to get there. I suggest you focus on fixing you tables instead of placing a band aid on this query.
