BUG? Invalid use of an Aggregate Calculation

Question

Please Help:
I am trying to create a mandatory Filter in a BU that is
COUNT_DISTINCT(ID) > 3;
When Mandatory an error pops up:
Invalid use of an Aggregate Calculation
If Optional filter works and can be used in a workbook.
This should be allowed. The filter will require that all rows be based on at least 4 Individuals (required for privacy) and no single individual be retrieved.
Is this expected behavior?
Thanks

Just a follow-up: I did post a TAR.
Yes this feature is documented, AND no it is not important enough to change. (I added the last part of commentary).
I will post a snip of the TAR just in case others run afoul of this "Feature".

A:
Unfortunately you cannot use analytic functions in Mandatory conditions, you can see this in the Oracle Discoverer Administrator Administration Guide, I'm copying what is documented and the complete reference:
"When you create a condition based on an analytic function (i.e. a function that computes aggregate values based on a group of rows), you must designate the condition Type as optional. If you choose mandatory, a message is displayed informing you that analytic functions are not allowed in mandatory conditions."
"What restrictions apply to aggregate calculated items?
When creating aggregate calculated items, note that a number of restrictions apply to aggregate calculations. Aggregate calculated items:
cannot be used in a mandatory condition
From:
Oracle® Discoverer Administrator
Administration Guide
10g (9.0.4)
Part No. B10270-01
Chapters:
11. Creating and maintaining conditions, page 11-6
10. Creating and maintaining calculated items,
Section: What restrictions apply to aggregate calculated items?, page 10-4
A way to workaround this, could be creating a view in the database based on the select count distinct, then create a folder in your Bussines Area using that view and create the Mandatory condition based on that Folder.
Let me know if you have any additional questions regarding this.
Best regards.

New info :
We will be unable to use Discoverer, again. This may be the last chance for its Implementation in our Organization. With Apache, Tomcat, php, etc, it is looking bad for Oracle Application Server in general.
Thanks for your help.
