Sir

 

I have a problem with displaying negative floats in my project during progress updation. I have put a must finish contraint to the activities. But activities whose actual start and actual finish are entered does not display negative float, though its supposed to be showing a negative float. Plz help :)

    Activties which are complete

    Activties which are complete do not have float.

    Float is a measure of how much time an activity could be delayed by before delaying the project. This measure is meaningless for an activity which has already been completed, since it cannot be delayed.

     

    Also please note that using must finish constraints is generally considered bad practise, as it disrupts float calculations.

    I agree with Gary. Perhaps

    I agree with Gary. Perhaps what you wanted to show are the variance of the actual dates from the baseline date. Use variance instead of floats. I am just guessing of your intention.
