Hi Melvin, Latest P6 based the summary (if calendar is not the same for all activities under that WBS) from Project Calendar not from Default calendar. Here's from P6 Help, "if all the activities are not using the same calendar, then the values are calculated as follows:
If all the activities under the group band are in the same project, then rolled up duration and unit values are calculated using the project’s default calendar.
If all activities under the group band do not belong to the same project, then rolled up duration and unit values are calculated using the default global calendar."
