I have two columns of data, Manager and Employee.
For every Manager, the corresponding column value has their employee.
there are duplicate entries of manager so every employee is covered.
Some employees are aslo managers so appear in bolth columns.
I want to find all the managers that fall under only one of the managers.
Finding the first level of employees under that manager is simple, but some of those employees are also managers.
And under those are more managers.

Suggestions?
Thanks.
