RE: How to build Org chart into CRM
Struggling a bit in terms of language but let me iterate what I THINK you're saying and then you can tell us what I got wrong :
-You've created OU's for Business Dept's 01 and 02.
-You've created roles for Manager 01 and 02
-You've created roles for Admin 01 and 02 (which would seem to have the same access as the Managers)
-Each staff member has a role (staff A-F)
-Contact records are owned by each staff member individually
You want to insert a layer between the staff members and the admin/manager role (since your diagram depicts a 1:1 relationship, I see them as a single role) you are calling "Leader" which have a 1:1 relationship to the staff member (ex. "Staff A" belongs to "Leader 01" and "Staff B" belongs to "Leader 02"). That's what I think I understand from your diagram. Is that correct so far?
If that is correct, you want to make sure that no one from the Dep't 02 tree can see any records belonging to any staff members in the Dep't 01 tree. Is that correct?
