Hello Planners
Who explain the following discrepancies between the original duration of a sequence of tasks and of the corresponding WBS level?
I have scheduled 4 tasks on line with Finish to Start links, no delays; the total duration of the sequence is 55 days, starting the 1st of September 2007, and finishing the 18th of November; the working week is Sat - Wed and I have entered 2 holidays: Oct 13 and 14.
A) Why does PM5 / PM6 show a 54 day duration for the WBS level? I have checked the number of working days between Sept 1 in the morning and Nov 18 in the evening: 55
B) Why does PM5 change the WBS level duration to 52 when I delete the additional days off, and not when I only delete Oct 13?
I have carefully checked that both the project and the tasks are using the same calendar; this calendar is not PM5’s default calendar; I have checked that the Admin and User Preferences Units are according to the calendar, i.e. one week = 40 hours
I do have the same problem when using PM5 and PM6 on several PCs, and in several projects
Thanks for your help,
Alexandre

Oldest first- 0David Kelly ·The duration shown in a WBS activity is based on the WBS activity’s calendar. When you press F9, the WBS duration is back-calculated based on it’s start and finish dates on the calendar you have chosen.
***** NOTE ******
The duration of a level-of-effort activity is based on the Early dates of the hammocked activities, a WBS summary is based on Planned dates BE CAREFULL!!
