filter required for critical path

Hi John,



Longest path is not equal to a filter having TF=0



Check this link of Ron winter’s paper on longest path. Beautifully written and explained.

John,



As I develop and identiy critical paths I give the affected activities an activity code specific to that path. This way I can make specific views for these paths and log their existence. It also allows me to effectively communicate the importance of certain otherwise minor activities with better reason than "the total float is low" which just tends to get sneered at by the executors.



Of course your method of filtering for total float < whatever is also good, especially at finding previously unknown critical or near critical paths.





Wael,



Use Tools/project utilities/Export... to export the variance data to DBF. Then you can open it in excel and analyze to your heart’s content. you could conceivably use custom a data item to store the result of the column subtraction but it is indepth, a pain nit he @rs3 and requires use of Global changes, which I am generally against where not necessary (and in this case export to DBF will do what you want, I believe)

my friend set your filter to longestpath EQ yes

you will get the longestest path , consider it to be the critical path. by that you can regulate the float and set it to around zero... thus you will be mostly efficient.

now if you wish, i have a question of my own..my friend ,

i might be facing a simillar problem yet since i am introduced to primavera since a very short time i wish if you can help me in what i am facing.

i wish to ask again some specific and nore challenging question regarding the use of primavera.

i am stuck on a stage where i want to find the difference between the variance at early start and the variance at early finish. all i need to know is how to perform column subtraction in primavera?

i tried using the converter to excel and do it there yet i am facing a proplem since MPX does not copy the primavera activity ID. what shall i do?

yours always , wael el hajj
