Do the individual activities duration changed by a factor of 8?



Planning unit might be an issue in adittion to all previously mentionted reasons.

Thank u fellows, but the problem is not being solved, ive tried to create a completely new data base, but still not working i think the reason is that this schedule is prepared using P3 then it was converted to P6, which created many conflicts.



i will try other things, later ill let you know what was the problem.



Thank u all,

Hi Jawad,



In additon to Dieter and David info. One more reason is, when the .XER format sent to you has already a start date, it means that project is already started or in progress.



May be the reason is when you press F9, try to check the "Options" General Tab, "When scheduling progressed activities use:



1. Retained Logic

2. Progress Override

3. Actual Dates



When "Retained Logic" selected and the finish date changes significantly, then there is a lot of out-of-sequence activities that is affecting the critical path. That is why the original duration changes. Try to shift to "Progress Override" and schedule again.



Regards,



Arnold

The total project duration as measured by the rolled up duration column is based on the database’s default calendar. If the two databases involved have different default calendars the durations will be different

Hi Jawad



Create a baseline after importing BEFORE! F9. It will be easier to locate the reason.



Check the calendars for same name but different contents - e.g. holidays, working hours, hours per day



Admin Preferences: Hours per day is another candidate.



Good luck!



Dieter
