Propagation of Profile Level Permissions
In addition to propagating permissions that control the access to an asset instance (as described above), it is also possible to propagate permissions that control the access to the asset instance's profiles. This means that the profile permissions that you define for an asset instance can be propagated to the asset's dependent assets. However, this is only possible if the dependent object is of the same asset type as the first object; this restriction arises because different asset types can have different sets of profiles.
This behavior is activated when you mark the checkbox Propagate profile permissions in the asset's Advanced Settings.
