Float affected by external projects

In the Open Standard

Afternoon all,

I have a project plan from a contractor which I have linked directly to my plan so it drives my dates when I F9 my plan.  However the contractor is saying he's seeing negative float appearing in his plan and we're wondering if this can be caused by linking it to mine.   The links only go one way from his to mine just to update certain milestones in my plan to make it easier for people to see and our central reporting to pull those dates out and report on them.

Is this a possibility, I can't see how but I'd rather not affect his details so want to be sure.

thanks in advance,

Thom

    1. make sure that that data

    1. make sure that that data dates are the same 

    2. have him look at his negative float activities and look at the predecessor activities add a column in the predecessor window that shows the project and see if the predecessors that are driving and critical are coming form your project.

    3. go to schedule then options then check ignore relationships to and from other projects then press f9 and see if the negative float is still there.

    Hi Zoltan,My project only has

    Hi Zoltan,

    My project only has successors from his project, nothing goes from mine to his it's purely to update dates in mine once he has updated them in his.

    I will tell him to try the ignore relationships, however will this then stop his updating mine?

     

    cheers

    your successor is a

    your successor is a predecessor to his work. you also have the option to turn off the external relationships within oyur project.

    Nowhen he F9s, have him not

    No

    when he F9s, have him not open your file and select "Ignore relationships to and from other projects" (non opened projects)

    you can then choose to not ignore when you F9

     

    are these interdependency milestones constrained? if so, STOP that! use a variance against baseline targets for reporting and allow the true successor relationship with your project to drive the float back into his project. Just my opinion.
