As an interface to the user, the presentation layer contains software components (the SAP GUI) by means of which the user is presented with the application. During its runtime, an SAP GUI component is always permanently linked to a user logon to the NetWeaver AS ABAP.
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.

A trick often used by administrators is to allow for time buffers before starting the next job. The buffer times are necessary because it is not possible to predict exactly how long a job will take to complete, since the duration depends on many incalculable parameters. Since it makes little sense to run backups and SAP jobs at the same time, these tasks are usually done one after the other rather than in parallel. In more complex environments, data backup durations, time buffers and job runtimes add up to such an extent that the time available is no longer sufficient to perform all activities within the available time corridor. Tools that work with status dependencies and then automatically start the next job when its predecessor job has been processed without errors can help here.
Regular maintenance tasks or the standard procedures must be described and defined to build checklists based on them and to control compliance with this standard. The SAPSolution-Manager can also support this as a tool of SAP e.g. through the Guided Procedures. In this context, it is also necessary to document the functionality of an underlying application and thereby determine what testing and monitoring activities are necessary. This is a reconciliation process between the SAP basis, other IT departments and, if necessary, the business areas concerned. The defined standard and the system's IST situation must be fully documented and regularly checked for compliance. This can be done through automated monitoring, validation using tools such as SAP-LVM (Landscape Virtualisation Management) or SAP Solution Manager, as well as manual checklists. Only the regular review of the standards guarantees their compliance. It can also support the regular use of SAP services such as Go-live Checks or Early Watch. Examples of how to standardise procedures are listed here: ・ Naming of system instances and logical hosts, or at least one central registry in a directory service, or LVM or SAP customer portal ・ Centrally starting and stopping systems, such as via the LVM ・ Categorising SAP instances by T-shirt size to define profile standards and cost them.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
