Software maintenance of SAP® systems
Automatic error handling when a job is aborted is desirable and useful in most cases. The conscious processing and consideration of error situations in job chains - also at step level - can help to reduce manual effort. Error situations should be catchable: If they are non-critical elements, the following job can perhaps be started anyway. In the case of critical errors, a new attempt should be made or an alert issued so that an administrator can intervene manually. Simple batch jobs are usually not capable of this. The goal of an automated environment is not to have to react manually to every faulty job.
Standardisation of SAP operations as well as SAP systems can be seen as a preparation for automation as well as for cloud, outtasking and outsourcing service forms. Therefore, in the whole context of standardisation and automation, a sequence of tasks and systems needs to be followed. To do this, it is necessary to first make a detailed documentation of the respective object, which also describes the IST state in detail. A standardisation strategy can then be developed, defined and implemented. Only then can we consider automation, outtasking, cloud, and outsourcing.

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.
Critical business processes require a secure, efficient and stable operation of an SAP system landscape. High demands on the management as well as the operation of the underlying SAP NetWeaver platform require competent support in all tasks of planning, support and updating of the SAP Basis. The increase in installed components as well as systems integrated via interfaces expands these needs. Only with professional care and maintenance of its components can SAP NetWeaver bring its advantages as an integrative platform to bear.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
Within the layer there are application servers and a message server.
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.

Technically, SAP Basis consists of three layers: the database layer, the application layer and the presentation layer.
