!!! Overview
[{$pagename}] or ([PP]) determines where new objects are placed and what they are named in the Identity Vault and the connected application.

The [{$pagename}] is applied ONLY to <add> events and serves to generate a name for a new object and to generate a placement in the target object [hierarchy] The [Subscriber Channel] and [Publisher Channel] which usually have different Placement Polices.

The [{$pagename}] is executed after the [Creation Policy Set] and before the [Command Transformation Policy Set]. Note that the [{$pagename}] will not be executed if the Create Policy vetoes the <add> event.

A [{$pagename}] is required within the [Publisher Flow] if you want object creation to occur in the [IDV] the and the [{$pagename}] uses the [Policy Set Interval Value] of 13.

A [{$pagename}] might not be necessary on the [Subscriber Flow] even if you want object creations to occur in the connected application, depending on the nature of the destination data store. The [Subscriber Flow] [{$pagename}] uses the [Policy Set Interval Value] of 12.

For example, no [{$pagename}] is needed when synchronizing to a relational database because rows in relational database tables do not have a location or a name.
