Mapping to the PCD Path 
You can base the ID prefix for each object on the object's location.
For example, if you create an object in the folder structure , the prefix is required to be myFolder1.myFolder2.
For the NamingConventionsSrv service, set the following properties:
Activate namespaces: true
Mode: path.
For more information on configuring the NamingConventionsSrv service, see Configuring the Service.
Administrators no longer can enter any prefix for objects, but must select the prefix based on the object's path.
