SAP's client concept enables a SAP system to be split into several logical sub-systems - clients. These subsystems can be used independently and in isolation as separate systems. But how should non-client transactions be treated? How can you prevent one client from accessing the other and why should you want to prevent that? In this blog post, I will answer these questions and discuss some negative examples. Why is it important to consider independent transactions separately? Imagine that every one of your employees is allowed to create or change a client in the production system, or worse, both. Creating and modifying a client in the production system is authorised and documented - you wonder what could possibly go wrong?

The core of the three-layer model is the application layer. This consists of one or more application servers and a message server. Companies use the application server to provide services for the operation of applications in SAP.

Furthermore, the data is prepared for the user in the application view so that the user can call up the data visually in the presentation layer. At the same time, the user data is forwarded to the database.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
