Date Constraints suddenly appearing

Help

  • Hi all,

    I'm having trouble moving my tasks around on my gantt chart.
    Initially there are no constraints set on the task, but if I change the start date, (suddenly) a "Start no earlier than" constraint will be applied!

    From then on, I can only move the task to be started at a later date. I cannot move it to an earlier date, its a like a one-way street!

    If I go into the advanced tab of the task info and try to delete the Constraint Date, the constraint will be removed... but will instantly re-appear if I try to change the start date of the task again!

    Effectively this means that I can't move my tasks around.
    Is this default behaviour?

    I have found, as a work-around, that I can move my tasks around by changing the Constraint Date in the Task Info dialogue... But this is a bit of a pain.

    Can anyone help?

      I'm having a similar problem: I have a summary task with one subtask of one day's duration which occurs on 1/15/2009. As soon as I add another subtask, it immediately places that new task to start at 2/26/2009, which is completely crazy.  The task shows "As Soon As Possible", has no constraint date, and has no resources assigned so it's not trying to level anything.

      This is a complete show-stopper on this project -- if I can't get OpenProj to place tasks where I want them, it's not much use... hopefully, this is some kind of obscure pilot error that someone can help me get around.

      Thanks...jon

        Answering my own question...

        Somehow the summary task had gotten a "start no earlier than" date constraint, so everything I tried to add as a subtask took that as a starting point.

        In general, if you manually set a date, then a date constraint of some kind is added and then I have to go to the Advanced tab... as I recall, this is very much like MS Project.

        cheers...jon
