Naming Conventions for Namespaces 
By default, the portal allows administrators to create PCD objects - such as iViews, pages, worksets and systems - and enter any string for the object's ID prefix (namespace). By activating and configuring the naming conventions feature, you can set naming conventions for object ID prefixes.
You can require that ID prefixes be based on the administrator who is creating or changing the object, or on the PCD path of the object.
The naming conventions feature is controlled by the NamingConventionsSrv, which is contained in the com.sap.portal.namingconventions application.
Note
The feature controls ID prefixes when an administrator creates an object or changes the object's ID. It does not check prefixes for the following:
Imported content
Copied content
Content from content mirroring
