The second component of the application layer is the message server. It acts as a kind of "mediator" between the services and the applications.
The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer.

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.
