Cross-schedule Critical Paths

there are two options

option #1

filter for longest path 

option #2

create a global code call it Mypath

make the code value MP for my path

add this column to the view

filter for the last activity in the schedule 

look at its predecessors and look for the one that is checked DRIVING AND CRITICAL

now in the predecessor window highlight that activity and then click on GoTo

keep doing this until you get back to the data date or the start of the project.

now in the column that you just added (MYPATH) put in the code MP

now do a fill down for all of the activities that are on your screen

now filter where Mypath equals MP

now you have it 

This is one of the scheduling options. 

1) when you open more than one project, the scheduling options for the group are determined by the "Default project" (set under the Project main menu tab)

2) That Default project should have the "Calculate Total Float" option set for "Opened Project"

You now have a single scheduling entity, no matter how many projects are open
