Hi.
PowerProject software can solve this problem.
This is the typical feature which I think PowerProject is stronger than Primavera.
Hi Andrew.
Could you send me that technical paper?
Thanks & regards
Guys,
This problem is as a result of the global calendars and default units per time period, combined with resource and activity calendars.
Basically Primaveras standard line is "thats how the software was designed"
I have written a small technical paper/benchmark to try and illeviate this error, drop me a line at [email protected] and Ill send you a copy.
Have a look at it and tell me what you think.
The downside is that you may loose some enterprise functionality as advertised by Primavera, but at the end of the day we just need the K.I.S.S. principle and not all the bells and whistles that they have tried to give us.

hi,
that wont help if you have different calendars for different activities. This concern has been raised on more than one occasion directly to Primavera CEO during middle east annual primavera conference & we have not got any response on this. So the best way to avoid confusion is to hide the summary durations.

Hi.
Or you can set the default calendar same as activity calendar.
In P6 all summary durations, for all projects for all sub-totals (e.g. each WBS) as well as the total project duration are calculated the same way.
The duration is set as the number of workperiods between the start and finish dates on the databases default calander.
So in your example the database default calendar is NOT the same as the calendar on your activities.
SOLUTION
Set the rolled up totals OFF in "Group and sort"
Add an Loe OR WBS summary activity with the calendar you want to use for calculating the summary duration.
