SYSTEM
Integration / Interfaces
The presentation layer is the top layer of the R/3 SAP Basis system and includes the communication with the user. Here, the data is graphically prepared for the user on the end device by means of software components from the application programs of the application layer. The presentation layer is the interface to the user (SAP GUI).
In addition to internal security requirements, national and international guidelines sometimes require all audit and security-related user actions to be recorded. With the Security Audit Log (SAL) you have the possibility to log all changes, e.g. for users, user master records, but also roles and groups.

Database layer: All of a company's data is stored in the database, which is located on a database server. Application programs pull the data they need from the database. This data can consist of data tables, applications or system control tables. In addition, the database also takes new information from users and backs it up.
The website www.sap-corner.de offers many useful information about SAP basis.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
I recommend that you schedule the background job PFCG_TIME_DEPENDENCY with the report RHAUTUPD_NEW. Scheduling the RHAUTUPD_NEW report with two variants has proven to be a best practice: Once a day before users log on for the first time (e.g. midnight or very early in the morning). This way the users are synchronized once a day. Once a month (or even once a week) with the option "Perform cleanup", so that obsolete profiles and user mappings are regularly cleaned up. Also handy: If the naming conventions of your roles allow it, you can also align the report according to different time zones. For example, I have a customer who runs the user synchronization for his users in the USA and Asia at different times, so that the daily business of the respective users is not disturbed.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
I_FORCE_DELETE The logical name of the BW system.
This is partly due to the late consultation of the SAP basis on the issues of technical feasibility as well as the integration of new technologies and applications into the existing system landscape.
