Hi, thank you for you'r answer.
After a few tries, I will take the option to create a new folder and delete the AP which does not interest me.
First I don't understand the difference between new group and new folder. A group is composed of folder ?
I don't found where i can't create a new folder on Aruba, i can create only new group.
So i wanna create a new group but this new group of devices will be used only for report generation and should only be secondary to the first. The first group already in place takes care of capturing all aruba devices without exception.
