Problems in the duration

Orozco,

If you wan to use a 24hr calendar define work hours/days/month as follows.

Go to Tools/Change Working Time/Options and make;

Hours per day = 24.00
Hours per week = 168.00
Days per month = 30.00

Best regards.

Hi Rafael Thanks but if you saw my project file the problem isn’t the 24 hours calendar...cause i did it that you say me...but the wrong duration still in my project.

Are you getting this? About 25.42 days?



Using a Standard Calendar as per your definition I got the following. Perhaps constraints are having a different impact on total duration depending on calendar. Hammer Rule would be handy, hit it with a hammer until it fits.

Orozco,

Your problem is probably caused by a good mix of calendars and that some of the settings are wrong before starting to entering task.

Under Format-Options-Calendar you state that a day is defined as 14 hrs, but the Estándar calendar only allows them to work 10 hrs – and the Estándar calendar is still applied to all your resources. Furthermore, you have default start time of the day set as 07.00 (also the Calendar-tab).

Now you suddenly change the project to a 24 hrs calendar, meaning that all tasks that don’t have any calendar assigned to them (=None) take upon this 24 hrs calendar, however, the Estándar-calendar is still assigned to all resources with only 10 hrs of allowable working time per day and a day defined as 14 hrs starting at 07:00 and not 00:00 when you have a 24 hrs calendar. Furthermore, all your tasks are defined as fixed units, meaning the duration will change as you change calendar and there are a SNET-constraint set to start at 07:00. All in all, you can’t almost avoid to end up with odd comma-days.

My suggestion – and as you only have 18 activities – start a new project, get the settings correct (the maths have to agree), be aware of which calendar is assigned to the task, which calendar is assigned to the resources, how a day is defined by MSP, etc.
