Custom Folder SQL Error

Question

Hi,
I am constantly getting the following error trying to create a custom folder in Disc Admin 9.02.00.00
"The custom SQL entered contains enhanced aggregation and is therefore invalid"
The first time I tried to create the folder the SQL did have aggregation ie:
select dim3.group_id, dim3.description, sum(fact2.revenue)
from dim3, fact2
where dim3.group_id = fact2.group_id
group by dim3.group_id, dim3.description
Q1. Can you aggregate like this in a custom foler?
But I still get the error without aggregation ie:
select dim3.group_id, dim3.description, fact2.revenue
from dim3, fact2
where dim3.group_id = fact2.group_id
and even with:
select dim3.group_id from dim3
I have restarted admin a couple of times but that has not helped.
Q2. Why am I still getting the above error message with the simpler SQL statements.
Thanks Phil

Answer 1

PS: I also tried creating the folder in a new business area with the SQL:
select dim3.group_id from dim3
