Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Hi to all,

As we know that in Primavera v3.1 the default column for early dates is Early Start & Early Finish.

But in the Primavera v.6 the default column for early dates is Start & Finish but when you i am inserting column of Early Start & Early Finish in these column showing nothing.

So can somebody explain difference between Start & Finish vs Early Start & Early Finish according to Primavera P6.

regards........

Have a look at a paper that I co-presented at the 2009 AACE International Conference called " Understanding P6 Dates." I think that that should help answer your question. It is much more complicated that you would imagine.

Irfan,
Early start is the earliest start date where activity starts and early finish is the earliest finish date where activity finishes.
When planner develop the schedule this is the planned date = early date = start date.
Start date is the current date. When activities have start progressing start date become actual date and early start = Remaining Start
