SPAM permissions

You will learn the most important administrative tasks, such as user administration and roles, the SAP data transport system, security in the SAP environment, administrative background tasks and system monitoring.
This is where all the system's data resides. These are composed of the actual database and the DBMS, the "database management system". In earlier versions, the database here came from different manufacturers. For example, Microsoft SQL or Oracle. Since SAP HANA, a lot has changed for IT in this data layer. This is because the database comes from SAP itself and is automatically monitored by the system. There is more to this database layer than just the working data. Important elements such as the configuration tables and system data for control and application content are also stored here. This is the repository data used by applications.
Monthly reporting / reviews
In addition to the consultants working in the individual SAP modules, there is a subarea here that is not directly apparent to many and whose activities seem to be quite opaque: SAP Basis. The smooth operation of SAP systems as the heart of many companies is ensured by the work of SAP Basis administrators.
Application layer: The application layer is the central component of the SAP ERP system and is therefore also referred to as the base system. All applications and calculations are executed here. The application layer communicates with both the database layer and the presentation layer. On the one hand, it requests data from the database layer, processes it and then passes it on to the presentation layer. On the other hand, data that is newly entered in the presentation layer is passed on to the database layer and stored there.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
In each NetWeaver system there is a database server on which the SAP database is located.
The website www.sap-corner.de offers many useful information about SAP basis.
