How can I check which Global Collections a device is a member of
To check which Global Collections a device is a member of do the following:
Select the device and from the component detail window go to the information tab.
Go to the global collections memberships sub view and expand the view.
From here you can check which static and which global collections the device is member of.
Alternatively from the attributes tab of the device the CollectionsModelNameString attribute will show which GCs a device is in.
