Here is the little scenario I would like to clarify:
1. I create a 10 days task T1 with all default settings ( type= fixed units, duration=80hours, workload=80 hours)
2. If I assign one resource R1 to it, resource is allocated for 100% for the duration of the task. So far, so good.
3A. If I remove the resource R1 and THEN reassign 2 resources R1 and R2, both are allocated for 100% and the duration of the task drops to 40hours/5 days (task work remains unchanged at 80hours). So far, still good.
3B. Now, if instead of removing R1 first, I keep R1 assigned to T1 and add R2, then both resources are assigned to T1 for 100% but the duration of the task drops to 20hours and the work for the task drops to 40 hours.I would have expected the result of 3B to be the same as 3A.
Could someone please help me clarify what I am missing ?
