Copy parts of project

Hi Schedulers,

I want to copy a part of the major project to create a smaller schedule, because its faster, safe, etc..

but.....

He don’t do it...

In the major project i run a filter en then I "Select all" and Copy (Ctrl-C)
I go to the schedule I want to paste, but it is not working

Please,

Can anybody tell me how to copy only parts of a schedule in an other schedule ?
