SAP Security can be re-used by QlikView and as you have already mentioned, section access applied on top to restrict what users can or cant see within the application.
SAP Security Roles and Authorizations are stored in a number of different tables which can be extracted using the QlikView SAP SQL extractor. Once stored in .QVD format in QlikView, then section access can be applied.
I would suggest that your SAP Basis team would be well placed to advise you which tables you will require to apply the appropriate level of security.
We implemented SAP BW Analysis Authorizations in our QlikView dashboards (using Section Access)
Please take a look at the following thread, on which I gave detailed response:
If you require any examples, I can send it
That is a very helpful explication Yaniv!
Unfortunately as QlikView is implemented on the 'business side' in our company, that means that I as developer (working for the business) can bypass those security settings without the SAP crew knowing about it. I could create a report that has all the information, also that which i'm not allowed to see. I bet my SAP team won't be that happy about this. (which will most likely mean that QlikView won't receive any SAP data).
