SAP NetWeaver Portal provides you with functions for the creation and administration of roles and users.
To access connected ABAP-based back-end systems with the roles managed in the portal, you must transfer these role definitions and user assignments to the ABAP systems. For this distribution process, a component in the portal is available, which allows you to distribute the portal roles and user assignments to the ABAP system.
Data on the following services can be transferred from the portal to the ABAP system:
Transactions
Nontransactional data (for example, TADIR services or RFC-enabled function modules) in the form of authorization trace IDs
On the ABAP system side, transaction WP3R is available. This enables you to assign a corresponding role in the ABAP system to users and their assigned portal roles. The corresponding role (authorization role) contains the authorizations that are required to perform certain services, for example, transactions, from within the portal.
