In the SAP product world, the presentation layer is based on several modules that are grouped under the collective term SAP GUI. SAP GUI for Windows, SAP GUI for Java, Web Dynpro for ABAP (WDA) and SAP GUI for HTML ("Web GUI") are widely used.
Basis comprises a number of middleware programs and tools from SAP. Basis is responsible for the smooth operation of the SAP Basis system and thus for R/3 and SAP ERP, for example. SAP thus provides the underlying basis (hence the name) that enables various SAP applications to be interoperable and portable across operating systems and databases.
CREATING NEW ROLES
PROJECT HISTORIES: THE SAP basis OF TOMORROW An entry in the Forum Infrastructure and Operations within the DSAGNet drew attention to the problem of the SAP basis as described above. This led to a lively discussion, which attracted a lot of interest from the members of the DSAM. Building on the interest and need for action of the member companies, a project was initiated by the DSAG as well as by the SAP, which should deal with the future of the SAP basis. Several companies were invited to participate and their willingness to participate actively was questioned in a DSAG survey. The first project meeting took place within the framework of the DSAG Annual Congress in Bremen in 2015. As a result, regular events took place at the SAP office in Freiberg am Neckar and St Leon-Rot, with the participation of up to 15 companies. In the project "the SAP basis of Tomorrow", current questions of the companies as well as the question of the SAP basis of the future were discussed and worked out with regard to the IT landscape, processes and organisational structure. A master's thesis was initiated to document and prepare the results as well as to examine the topic in scientific terms in parallel with the project. This was made at the University of Applied Sciences Würzburg-Schweinfurt as part of the Master's programme in Information Systems with Prof. Dr. Karl Liebschnitel and submitted for evaluation at the end of March 2016.
The so-called SAP message server also belongs to the application layer. Only one instance of this server exists in the system. It mediates between the services and applications. In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on. Communication between application servers is also the domain of this message server.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
It contains the following components:
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system.
