Discoverer Formula Column

Question

Hi
Hoping you can help with a formula column I need to create.
The situation is this:
It's for a HR head count report which is split by Employment category.
The issue is for multiple assignments, where in this report - I only want to count each person once, but not necessarily their Primary Assignment.
If we assume we have 3 employees, one of which has 2 assignments in different Employment Categories - each assignment has a head count of 1:
Employee A - Assignmnent AA - Employment Category A
Employee B - Assignment BB - Employment Category B
Employee C - Assignment CC - Employment Category A
Employee C - Assignment CD - Employment Category B.
As normal, the summed report of headcount would show
Employment Category A - 2
Employment Category B - 2
However, the way I need it to work is that the report will prioritise each employment category so that if an employee already has a record in Employment Category A, it won't count the record in Employment Category B. If the employee only has a record in Employment Category B, it will show though.
So the result I want is:
Employment Category A - 2
Employment Category B - 1
Is there a way for a formula to work out this priority and so only sum for Employment Category B where there doesn't exist an Employment Category A record for the same employee?
I hope I have explained this ok.
Many thanks

Hi
Thanks for that - I now have it working.
I am however having issues with Totals.
They are fine in Discoverer Plus but I need to run this report in Desktop.
In Desktop, I have totals for rows and totals for columns for both HeadCount and FTE.
Initially, none were showing.
After changing the aggregation option from 'Default aggregation behaviour' to 'Show the sum of the values', I now get everything except the grand total for HeadCount.
Example below
______________Head Count____________________________FTE
________Asg Cat 1______Asg Cat 2____Total______Asg Cat 1____Asg Cat 2______Total
Org1________2____________3__________5__________2____________3___________5
Org2________1____________2__________3__________1____________2___________3
Total________3____________5_____________________3____________5___________8
As you can see, I'm getting every total except the total of '8' for HeadCount but I am getting it for FTE.
I know this is often due to folder joins, but FTE and HeadCount are coming from the same folder, yet FTE is working and HeadCount isn't.
Any ideas?
Many thanks
Martin
