So you can see below how P6 honored the Fixed Duration & Units Duration Type and divided the work between the two labor resources at the point where the Technician was assigned. So in the above situation with our Electrician and Technician being assigned to an activity with a Duration Type of Fixed Duration & Units, we would see the Electrician’s effort get cut to 4 hours per day, and the Technician would also be recalculated to 4 hours per day, because that Duration Type preserves the overall hours to that of the first assigned 40 hours. This option instructs Primavera P6 to honor the Duration Type setting for the activity.
So preference setting ‘A’ “Preserve the Units, Duration and Units/Time for existing assignments” overrides the Duration Type and puts each resource on the activity with full default units/time values. This happens regardless of the activity’s Duration Type, which in this example had been set to Fixed Duration & Units. When we add the Technician, that resource also arrives with its default units/time setting of 8 hours per day.Īs you can see in the above figure, this gives the activity 80 hours of labor over the five days as evident in the Budgeted Units field in the Resources tab and the Budgeted Labor Units column. We assign the Electrician and that resource arrives with its default units/time setting of 8 hours per day. It will do this regardless of whatever Duration Type setting may be in place for the activity.įor example, we have a five day duration activity that requires one Electrician and one Technician. What this means in simple terms is that, when you assign a resource to an activity it will be assigned with its default Units/Time setting, and when a second resource is added to that same activity, Primavera P6 will assign that resource with its default Units/Time format. “When adding or removing multiple resources on activities…”Ī) – Preserve the Units, Duration and Units/Time for existing assignmentsī) – Recalculate the Units, Duration and Units/Time for existing assignments based on the activity Duration Type The title for the section is Resource Assignment and below that is the following statement. Let’s take a look at the options, and then I’ll explain what it all means.
Question: What do the options in the Resource Assignments section of the Calculation tab in the User Preferences dialog do?įrom time to time, I get asked about the setting in Primavera P6 Professional – Calculations User Preference and what impact it’s having on a schedule.
