unwanted decimals in duration field for tasks RRS feed

  • Question

  • I am working on a project and have set the calendar to 4 10hr days.  (7am-12:30pm, 1pm-5:30pm) also made sure to select 10 hour days, in the fields below when editing a calendar.

    this has caused some irregular problems in summary tasks even with just simple sub-task duration.  this only seems to crop up if the sub-tasks start or end date are changed after the initial calculation.  extending the duration of the sub-tasks will just change the summary task duration by the same amount.

    example: (expected and initial output)

    summary 1  duration: 4 days   start: 11/1/14   end: 11/3/14

    task 1:  duration 1 day  start: 11/1/14  end 11/1/14

    task 2:  duration 2 days  start: 11/1/14  end 11/2/14

    task 3: duration 4 days  start: 11/2/14  end 11/5/14

    example (weird summary duration after start date manual change)

    summary 1  duration: 5.9 days   start: 11/1/14   end: 11/3/14

    task 1:  duration 1 day  start: 11/1/14  end 11/1/14

    task 2:  duration 2 days  start: 11/1/14  end 11/2/14

    task 3: duration 4 days  start: 11/3/14  end 11/6/14

    where does the decimal come from if all the tasks are set up to use 10 hour full days?  it is oddly specific for only having general inputs.

    looked into the gantt chart and zoomed in far enough to see the hours for each task. it seems like when the date was changed, the start time for that task was set to 5am (2 hours before it was supposed to) and it seems to do this (but not always to the same time, but always before working hours) whenever a task has it's start date moved.

  • efrizzell,

    It will be a lot easier to see what is going on by going to File/Options/General tab and selecting a date format that includes the time. The dates by themselves don't tell us anything. Also, you show three tasks but are they linked in some way? If so, how (e.g. FS)?

    I assume you set up a custom calendar with the work shifts your specified, and it sounds like you also set the definition of a day (File/Options/Schedule tab) at 10h). That's good but that's not all you need to do. You also need to go to Project/Properties group/Project Information and set the reset the start date so it starts at 7:00AM. I'm guessing it still shows the default 8:00AM. Also in the Project Information window be sure to select the calendar as your custom calendar. If you have resources assigned, make sure the base calendar for each resource is set for your custom calendar.

    Once all that is set up, let us know how it works and if you still have an issue, show us the details and we'll help you figure it out.

  • that looked like it fixed the issue, thanks for the reply.  

    our tasks were not linked at all in this example other then all being under 1 summary task.

    looks like we were just did not know about the last part to go back into the project and reselect the time for 7am after allowing for a finer grain time
