Constraints - Where to use what??

Hi Haresh

The only constraint you should use is on the 1st task which should be start on or after.

All other uses distort the critical path.

Haresh,
You can google it and you find a lot of books and white papers available on the web.

Below link is one I found.
Adding Constrained Milestones

Rodel,

There are lots of book / materials available, if we search on internet, but there are fewer info available for all constraints, which we use in P6. i have studied the link what u have sent to me, that is helping me to some extent....

Can u send me some more useful links, with examples , in what external dependencies , we use constraints….Since I have to prepare for a presentation on this topic , I request you to provide this info….
Thanks in advance

Haresh,
You maybe searching a wrong topic. Try good scheduling practice or basic scheduling... etc.

In addition P3.x constrain equivalent to P6
P3 3.x Constraint Type:  ------------ P6 PM Constraint Type:

Late Start (start no later than)  ------ Start On or Before
Early Finish (finish no earlier than) - Finish On or After
Late Finish (finish no later than) ----- Finish On or Before
Start On ---------------------------------- Start On
Expected Finish ------------------------- Expected Finish Date
Mandatory Start ------------------------ Mandatory Start
Mandatory Finish ----------------------- Mandatory Finish
Zero Total Float ------------------------- Not Converted
Zero Free Float -------------------------- As Late As Possible
