Discoverer is pretty strict on what columns can be aggregated and which can not. And there is a reason for it...

You mention that you have 2 masters and 2 details in your report. Let's say you have the following data:

dept emp salary
10 A 1000
10 B 1500
20 C 1200
20 D 1300
30 E 1500

And another master-detail like:

dept region sales
10 X 120
20 Y 200
30 Y 150

Now, if we want to sum all numbers, it would be something like:

region sales salary
X 120 2500
Y 250 3000

This works.

But now, we want to add a "sublevel" dept:

region dept sales salary
X 10 120 2500
Y 20 ?? 1500
Y 30 ?? 1500

Discoverer notices this and refuses to give a total in this case.

By the way, please check of your joins are in "the correct direction" (master-detail defition in properties of the join), otherwise this behavior can occur more often than you want...
