INTEGRATION OF NEW TECHNOLOGIES - SUPPORT FOR NEW SCENARIOS
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.
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 basis system. Within the layer there are application servers and a message server.

Application layer: 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. Data that the user enters in the SAP GUI is passed on to the database via the application servers.
The Security Audit Log (SAL) is one of the most important elements when it comes to security in your SAP landscape. With SAL critical and security relevant activities in SAP systems can be recorded and evaluated. The settings in SAL are relevant for secure continuous operation.
"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP base.
When looking at the result, in addition to limiting the number of transactions that can be entered, another drawback of this variant becomes apparent: Although both associated roles are displayed, at first glance it is not possible to see which transaction is contained in which role.
There are potentially large security gaps here that allow access to server data.
