What do you think it is the best way to assign a Group ( ex. an AD group ) to an human activity ? Where it's "Responsable" you can assign the ID of the User only as far as i know...
I have a few ideas but i'm not sure if they will work... ( will have to do it really soon, and really fast though)
Ok i see that i was creating the group in the wrong place, think i have fix me problem.
