Qlikview SAP Connecter doesn't include a ready-made solution for SAP security.
However, almost all of SAP security is implemented in application database tables (whose data you see in PFCG etc..) Hence, it's possible to extract the data from these tables and implement it as security in QlikView applications.
I led such project that reflected SAP-BW analysis authorizations in QlikView Applications.
The SAP Connector comes with pre defined Role for Development and have to be adjusted to ensure all requirements for the SAP System are matched.
From the manual:
The Connector package includes Roles and Profiles, but these should be seen as suggestions to be used in development environments. Parts of the development process of the QlikView applications will be to create the necessary authorization in Production Roles.
