Propagation of Permissions
An asset can have one or more dependent assets. For example, a Service asset can refer to a WSDL which in turn can refer to one or more XML schema assets. You can optionally choose whether the permissions assigned to an asset instance should be automatically propagated to the asset instance's dependent assets.
In the context of CentraSite Control, propagation of permissions means that the new permissions completely replace the old permissions; the new permissions are not merged with the old permissions. As an alternative, you can use a change-time policy containing the action Set Instance and Profile Permissions. With this action, you can choose whether the new permissions will be merged with the old permissions or will replace the old permissions. For details, see the CentraSite Developer’s Guide
