Website Upgrade Incoming - we're working on a new look (and speed!) standby while we deliver the project

Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Dear all;
My activities linked by FS; and when I made a schedule I find the following for example;

Activity #1; Start 1/01/2010 Finish 10/01/2010
Activity #2; Start 10/01/2010 Finish 15/01/2010
Activity #3; Start 15/01/2010 Finish 18/01/2010
I wonder why because the normal must be:
Activity #1; Start 1/01/2010 Finish 10/01/2010
Activity #2; Start 11/01/2010 Finish 16/01/2010
Activity #3; Start 17/01/2010 Finish 20/01/2010
I need to solve this problem by the default way, because I solved it by add a lag =1 and I think it is not practical for big projects so can anybody help me by steps.
Best Regards,
Abeer Taher

Thanks Alexander;
It worked; I checked detailed work hours/day and made the following:
• From (0) to (7) non work
• From (8) to (15) work
• From (16) to (23) non work
I am very very happy
Best Regards,
Abeer

Hi Abeer

How are the working hours of the assigned calendar? If an activity is planned until the last minute of a day, the next one will start the first hour of the following day - some constellations with milestones can behave different.

Do you have preferences equivalent to as follows?
Assigned calendar activity 1: Working time 8am to 4pm, activity 2: from 9 am to 5 pm?

Of course you can use different calendars within one project - e.g. Engineering 5d 8h, transport 7d 24h, site 6 d 10h with different holidays. But, to follow Anoon’s words, don’t exaggerate: P6 can deal, but you can’t trace.

Regards

Dieter

Hi Abeer,

Dieter is right, and I supposed the result of logic depends on how you had defined it.

In your example, one of your activities has 5 days duration and uses a 7 day calendar, is there logic on it?

In my opinion, it is logical to tailor your calendar(s) and resources to your activities (after all, you are assigning resources to activities and not otherwise).

And by the way, use only FS

Hi Dieter,
I agreed with you about user reference, but I mean I don’t want to face FS problem again in future and for the existing project how can I make
Activity #2; Start 11/01/2010 08:00 Finish 16/01/2010 16:00 (calendar #B; 7 working days 8hrs/day)
Instead of existing; Activity #2; Start 10/01/2010 16:00 Finish 15/01/2010 16:00 (calendar #B; 7 working days 8hrs/day)
Thanks;
Abeer

Hi Abeer

What do you mean by "by default"? If you’ll work with days you must keep in mind that internally everything will be calculated in hours.
Before you’ll show a report, change your references.

Regards

Dieter

Dear Alexandre/Dieter,
Thanks for your fast replay I mad your steps and I found the following:
Activity #1; Start 1/01/2010 8:00 Finish 10/01/2010 16:00 (calendar #A; 6 working days 8hrs/day)
Activity #2; Start 10/01/2010 16:00 Finish 15/01/2010 16:00 (calendar #B; 7 working days 8hrs/day)
Activity #3; Start 15/01/2010 Finish 18/01/2010 (calendar #A; 6 working days 8hrs/day)

Well how I can solve this problem by default without need to show hours and minutes?
Best Regards,
Abeer

Taher

In addition to what Alexandre wrote change your user preferences to show hours and minutes:
Edit (in the menue) --> User Preferences --> Dates --> select show hours --> mark "Minutes". Then you’ll see the mismatch between calendar and your expectations.

P6 internally calculates in hours independent from what is displayed.

Regards
Dieter
