  • 1.  Task Durations Changing To Zero In MS Project

    Posted Jul 20, 2011 09:30 AM
    I am seeing a bizarre behavior and am hoping someone knows the solution. I have numerous tasks in Clarity with durations from 1 to 95 days yet when I open the project in MS Project these tasks all reset to a duration of zero days. I think it may just be a configuration issue but don't exactly where to look. Any ideas? TIA

    Tom

    What version of MSP are you using?

    Look at the offending tasks and resources assigned to the task, What is the % the resource is assigned to the task. If someone set the % to zero, then the duration will go to zero. - This is one of the most common reasons. if this is not the cause, let me know and I'll send the others.

    regards,
    Michael

    Here is my explanation from the 1st of May.

    This can happen in a rare case where a single resource is assigned to a task and the project manager then decides that the person is no longer needed on that task. Rather than deleting that assignment, the project manager zero‘s out the resource‘s assignment unit value. So with Duration = Work / Units, if Units is '0', then Duration will be '0', and TaDaaa, you have a milestone. (MSP will not give you a divide by 0 error)

    Note: Zero duration tasks are Milestones.
