COMPLY WITH ORDER OF OPTIMISATION
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 base system. Within the layer there are application servers and a message server.
Over time, the tasks associated with the base became more complex and time-consuming, so that only the consultants could handle them. A need arose to hire a person to deal only with Basis matters.
Understanding the structure and functionality of the system is especially important for IT administration. It's not for nothing that "SAP Basis Administrator" is a career field in its own right. Instead of data and application development, the focus here is on providing the software environment on which the company's tools are created. SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
Have you ever wondered what there is actually a tab personalisation for role maintenance in the PFCG or for user data maintenance in the SU01? I will answer this question for you in this blog post. What do we need the Personalisation tab for? This tab gives you access to the central repository for personalisation data. The purpose of this repository is to create a storage facility for user- and role-specific data without the need to create additional database tables. This data should then be taken into account in all manipulations of users and roles. The functionality initially includes a generic repository for user- and role-specific data and centralised access to that data by user and role maintenance. It also provides the ability to connect existing tables with user-specific data to the central access via a defined interface. To store personalisation data in the central repository, a key must be assigned to the data: This is done via the registration transaction PERSREG. The personalisation data that you create is stored in the generic drop table. Access to it is provided by the class methods of the CL_PERS_ADMIN class. Different levels of personalisation The data can be stored either to the user, to roles or to the system. A user can then read all data assigned to him (via role or his own settings) at once.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
It can also support the regular use of SAP services such as Go-live Checks or Early Watch.
Likewise, the SAP base system with the NetWeaver and HANA platform offers an environment in which the SAP programmes can run.
