How are the existing Areas manually assigned to a Personnel object affected when that Personnel is referenced to a Personnel Template that has existing Areas set to InheritFromTemplate.
Continuum Access Control
An existing site had manually assigned Areas to Personnel and wants to consolidate common Areas for groups of Personnel by using Personnel Templates with pre-defined Areas. It was unclear what would happen to existing Area assignments once the Template was assigned to the Personnel.
If you have manually assigned Areas to a Personnel and then attach a template, the AreaLinks in the Template will "compliment" the Areas you already had assigned to your Personnel. It will add any additional Areas in the Template.
As well, if you update your Template and add new Areas to it, these get pushed to all Personnel that are linked to that Template. If you delete Areas from the Template then this gets pushed out as well, unless the Personnel already had the Area assigned manually - in which case they retain access to it.
I guess the simplest way to think of it is that the relationship is like a binary OR operation.
Area Assigned = "Manually Added" OR "Defined in RefTemplate"
