So i have opened my schedule today in p6 and relised someone else has copy parts of my project into their's as they needed the same type of activities in there schedule.


However when they have copied and pasted the WBS it they seem to have had the Only between copied activiies un checked (in the copy activity options) and thus i now have hundreds of inter project links as it is maintaining those links from my schedule.


How can i quickly removed these as there are hundreds

Thanks for the post back.


I have check both the late and early exertnal finishs but the coloumns are blank.

The scheduling options is not ticked but i dont beleive the schedule will be affected by these links.


from what i understand my collegue has copied the WBS so all my activities have successor to their project but that is it, so they are all open ends.  It is just very confusing going to the successor box and seeing 15 links in that are of no use.


i can go through and delete but i have 2500 activities in my schedule to check.

now do a fill down a

Now do the same thing for the External Early Finish Column

Option #3

go to tools

global change

New (on the right)

Where  (leave this line blank)


External Early Start = (leave the rest of the line blank)
