Resources on LOE Activities

Hi there,

I am trying to set up a detailed schedule for an infrastructure project nowadays and my problem is about assigning a resource (say, Project Manager) to a Level of Effort activity. When I assign the resource to the activity, the budgeted units value is distributed uniformly over the duration of the task. However, I do not want to have it that way, so I go to the resource assingment window and manually adjust the manhour for each day. So far so good.

My problem begins when I schedule the program. As soon as I press F9 and run the schedule, all the adjustment I manually made on the manhours assigned to the LOE activity has gone. Again, P6 distributes budgeted units over the task span and I return to the beginning.

Is a there way that I can fix the manhours (manually adjusted) assigned to the LOE activity?

PS: I am still in the planning phase. So, no actual units/costs has been presented in the schedule.

Thanks in advance.

Regards.
