Hi Colleen,
As you know our approach was using Position and Control roles, we thought to use a BRF+ logic where owner of control role would be used a owner of Position role. But since we are planning to go by Business roles this requirement is ruled out, but i will try to come up with some logic to understand how this scenario could be implemented. I will give a try in BRF+ and will post my analysis so that based on that i can get guidance from the forum.
Thanks & Regards,
Sai.
