Technological basis for SAP Fiori (SAP Gateway)
SAP Basis - the secure foundation of the SAP system
In the past, when we deployed SAP environments, we first had to work out a detailed sizing and architecture and pass it on to the procurement team, which then ordered the systems and installed them in the data center. From there, it went on to the network team, the storage team, the operating system team, and the database team. So it was not uncommon for three to six months to pass between the architecture design and the installation of a new SAP system.
Presentation layer: The presentation layer is the top layer of the R/3 SAP Basis system and includes communication with the user. Here, the data is graphically prepared for the user on the terminal device by means of software components from the application programs of the application layer. The presentation layer represents the interface to the user (SAP GUI).
OS, Operating Systems
SWPM - the Software Provisioning Manager integrates the classical tools like sapinst, ehpup, etc. for the maintenance/installation of SAP systems.
Entry-level employees earn just under 40,000 euros per year. An employee with significant professional experience can look forward to around 90,000 euros. The average salary is 60,000 euros. However, these sums can vary depending on the company and location. The size of the respective company is also essential.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
Even for companies that hand over the operation of the basis to an external service provider, there are often still tasks from the user and authorization management environment at this point.
Often one is obliged to perform a migration.
