"SAP Security & Authorizations" is a course specially designed for students who are willing to take Quality training into SAP Security and Authorizations. As I don't believe in the slide show, I have made this course a practical one demonstrating the subject on live system. The course also discusses possible interview questions that you might face for that particular topic and also it unfolds some unknown technical secret tips and tricks about SAP Security which will help you to work smartly.
This course not only describes the subject in detail but also explains the topics technically and theoretically in detail with real-time examples thus making it easy for you to understand them soon.
As a gist, I would say this is the best course to start with if you want to learn "SAP Security".
