P3 keeps changing dates when I don’t want it to

Thanks for your help.. This program annoys me because it’s the first program I’ve ever used that I couldn’t just figure out how to use it on my own.

Hi Mike,



I suffered a similar issue to the dates moving here are some of the things that resolved it.



don’t forget to contrain the date!

if you are scheduling from a particular date and it is not constrained it will simply start the activity at the earliest possible time hence it moves it back to the data date



if it is being driven by another activity that finishes late this will push it out everytime you hit F9 so double check your predecessors.



I also found that if i was trying to replicate an MS project into P3, MSP allows activities to finish and start on the same day however if P3 is set to schedule in units of a day it will always start thefollowing activity the next day therefore pushing everything out.



Persevere hope it helps.

Yeah you’re right, it’s because that’s the Project’s finish date... I guess that wasn’t a good example. I give up on this useless program... I can make a better schedule with Paint

I don’t think I have "level automatically".. you can take a look in the screen shot. I made a simplified example, except in this example it created extra lead time and before it was creating lag time. In the new sample I want the project to end on Aprl 16, but you can see P3 creates lag time out til June 10 and I don’t know why??
