The Subscriber channel of the driver is the component responsible for synchronizing data from the Identity Vault, including data that was obtained from other authoritative data sources, into the SAP HR database. Because the SAP HR system is always viewed as an authoritative source of personnel object creation and deletion, the Subscriber channel is configured to only allow data to be queried, or read, from the SAP HR system, and to allow modification of existing object records.
The Subscriber channel is capable of synchronizing fewer data elements to SAP than the Publisher channel can synchronize to the Identity Vault. For data to flow from the Identity Vault to the SAP HR system, the driver utilizes SAP-released BAPI functions to make changes to employee records. Because of BAPI restrictions, the driver completely supports only the following infotype data:
Personal Data (Infotype 0002)
Private Address (Infotype 0006)
Communication (Infotype 0105)
Internal Data (Infotype 0032)
The system administrator specifically selects which attributes from these infotypes can be modified.
