Transaction code Description
CREATING NEW ROLES
The database layer is where all of a company's data is stored. In essence, it consists of a database management system (DBMS for short) and the data itself.

The application layer is the central component of the SAP R/3 system. This layer is therefore also referred to by SAP as the actual basis system. Within the layer there are application servers and a message server.

SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.

An SAP HANA system lives on applications. When you develop these applications, you should think about securing them early. Using HTTPS instead of HTTP is one of the basics. In addition, you ensure secure authentication and implement a Secure Software Development Lifecycle to ensure backup in your own developments. In your applications, you better start to check them for risks early on and run this backup process regularly. You can analyse and restrict access to source code later. Create a risk register and address security vulnerabilities in a risk-based manner. The later you discover a risk, the more expensive the fix will be. Further information on SAP Security in addition to the article can be found here. Do you have any further questions or suggestions concerning this topic? Would you like us to go further on the subject? I look forward to your feedback!

Mentioning the SUM tool leads us to another part of SAP Basis: system updates and upgrades. Since SAP software receives updates from SAP at regular intervals - in the case of R/3 in the form of SPS (Support Package Stacks) and in the case of S/4HANA in the form of FPS (Feature Pack Stacks) - a large part of an SAP Basis administrator's job is to import these packages into the SAP system.

For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.

You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, as well as client-independent customizing is allowed.

A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.


The application layer communicates with both the database layer and the presentation layer.
