I am sorry but not sure what you are really asking? Could you provide a use case so I better am able to answer your question?
I have a OP rule folder which contain 64 OpRules, I would like to activate the Device Groupes that belongs to it.
But for now I have to do it 64 times ... so if a way to click and activated them all in one shoot it would be great.
I am not aware of a way I have checked with each new version of BCM. If you find a way please post it.
If you select multiple ORs you are able to assign them. Same for schedule. Select those ORs which should have the same schedule, right click -> properties and edit the schedule for the selected ORs once.
If the ORs are already assigned and you only want to activate them you could navigate to the specific group, assigned objects, operational rules and select all ORs you want to activate.
If I understand well, your example show a group where multiples OR assigned to it, then yes
But my problem is I have one OR assigned to one Device group and that 64 times, so I have to activate 64 times
