Roger I don’t use resource pools, so this is just a thought. What difference does it make if schedule 1 and schedule 2 both think the resource will be used on the same 4 hours…as long as both combined don’t exceed the resource’s total availability. Assuming the resource calendar in the resource pool is 100% availability (8-5 so to speak), try setting the resource task assignments to 50% in the individual project schedules. Theoretically, you should get 4 hours in project 1 and 4 hours in project 2. Like I said, from a schedule perspective, does it really matter if the schedule thinks the work will be done from 8-12 of 1-5? Bottom line, you need four hours of work per day in that schedule. One possible result could also be that MS Project “stacks” tasks in the same schedule. Meaning Task A at 50% can be done in parallel with Task B at 50% because both combined don’t exceed the 100% Max Units defined in the resource pool for that resource. If that happens try adjusting the resource’s Max Units in the resource pool to 99%. Its a bit outside the box, but it might work.
