SAP BASIS - THE SECURE FOUNDATION OF THE SAP SYSTEM
Update/upgrade of databases
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.
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.

The presentation layer is the top layer of the R/3 SAP Basis system and includes the communication with the user. Here, the data is graphically prepared for the user on the end device by means of software components from the application programs of the application layer. The presentation layer is the interface to the user (SAP GUI).
To use all the features of the SAP Patch Manager, you need the following permissions: S_TRANSPRT S_CTS_ADMIN Both are in the S_A.SYSTEM permission profile. If you log in to the Mandant 000 and your user base contains the appropriate permission profile, then you can use all the features of the SAP Patch Manager. When you log in to another client or without the appropriate user profile, you can only use the display functions. Map this permission profile to the system administrator only. Only the system administrator should have permission to perform the following actions: Support Packages Download Support Packages Play Support Packages Confirm Successfully Recorded Support Packages Reset Support Package Status Support Packages eliminate errors in the SAP system or make necessary adjustments due to legal changes, for example. The affected objects will be replaced in your system. Each Support Package is valid for one release level (but for all databases and operating systems) and requires a precisely defined number of predecessors. The upgrade from the following release or revision level contains all support packages from the previous booths that were available until the upgrade was delivered. SPAM ensures that support packages are only played in the order specified. To avoid problems, play all support packages as they are deployed. This allows you to keep your system up to date.
