Dave,
Resource Plans are a 'planning' feature. they do not 'validate' the information you put in. The system does not prevent you from over-allocating a resource, whether it is project plans or resource plans. It does 'flag' them as overallocated both in the project
plan and the resource availability data. It is the job of the Resource Manager and PM to work and resolve those over-allocations.
Consider this scenario: Lets assume your FTE =8 hr/day, and you need Bob to work 16 hours on a specific day because of something mission-critical. DO you want the system to put a hard stop on allocating that resource for more than 1 FTE? I would say, I want
the system to allow it, but flag it, so that action can be taken to address the issue.
