To retire SAP applications, you need an SAP system user that includes remote function call (RFC) connection authorization.
For tables that store data in a readable format in the database layer, the retirement job uses the standard SAP database user to access data. The job accesses data directly from the database that hosts the SAP system. The SAP database user includes all of the required authorizations to retire an SAP application. You do not need to create or edit a database user.
For tables that store data in a readable format in the application layer, the retirement job uses an SAP system user to log in to the SAP system and access data.
After you install Data Archive and install the SAP transports for application retirement, you assign a role to the SAP system user. The SAP transports include the ZINFA_RETIREMENT_PREPARATION role. The role includes the rest of the required authorizations. You specify the SAP system user in the source connection properties.
