P6.1; WBS Total Original Duration Problem

The WBS duration is not a sum of the durations but a calculation based on the start and finish activities on the default calendar.

Dear Deepak,
Kindly note that the two activities have the same calendar,
So WBS total duration must be the sum of activities durations which = 9days not 8days

Check Global Calendar

WBS total Duration is calculated using Global Calendar and NOT using activity calendar.

This is still a enhancement request.

Thanks Raviraj,

You are right global calendar was 5 working days because most of rest WBS activities have the same working days and the mention below WBS activities is 6 working days.
But when I changed global calendar to 6 working days I found the following:
WBS title is Item #1, original duration was corrected to 9days instead of 8days
Other WBS’s sum durations increased from 1 to 3 days which is not correct for example WBS #2 included 2 activities with 5 working days;
-Activity #3; duration is (11days) start 06-May-10 (8:00) finish 20-May-10 (16:00)
-Activity #4 will start after finish activity #3; original duration is (1days) start 23-May-10 (8:00) finish 23-May-10 (16:00)
But WBS #2 sum duration = 15days instead of 12days.
So if I have many calendars at the same project what is the global calendar I must assign to make the schedule WBS’s sum durations is right and reasonable.

Hi Abeer,

From Rodel’s link, things might b very clear for u.

Here’s a workaround to overcome WBS bars problem:

- Set the rolled up totals OFF in Group and sort

- Add an LOE, OR

- Add WBS summary activity with the calendar you want to use for calculating the summary duration.

Cheers,
