Dear Planners,

Am getting error message "Not valid duration" however when I check I can’t see any incorrect data.

Anyone had this before and if so how did you resolve?

    When I open certain files and it occurs as I expand levels or scroll down through sections.

    Have discovered I have duplicated what ever it is, as one schedule I have expanded out now has the error occuring multiple times.

    Craig,

    Check the duration column, by mistake there may be some alphabets in duration for one or more activity.

    That’s the only thing i can see in it.

    Regards,
    Balaji

    Craig,
    while working with MS Project 2010, I also had these strange message, with no apparent reason; I cannot see any alphabets in the Duration field as Balaji is suggesting; could be a bug?
