SAP Basis Introduction and R3 Architecture Overview (in English)
Basis administration in the age of SAP HANA
ITIL stands for The IT Infrastructure Library. ITIL is a summary of "best practices" rules for professional implementation of IT service management. ITIL has established itself as an international standard in the area of IT business processes. The ITIL set of rules describes the processes, the organizational structure and the tools required for IT infrastructure. ITIL is based on the economic added value that IT operations provide for the company. itSMF Deutschland eV has further developed and improved these standards, and at the same time operates a portal for exchanging knowledge and experience.
SAP Basis or system administrators work with SAP Basis in a company. They are responsible for the correct installation, configuration and maintenance of the SAP application servers and applications, and in some companies also for the operating system and the SAP database if no administrators are available. Using SAP's own programming language ABAP, developers and programmers design SAP applications that run on the ABAP stack of the SAP NetWeaver Application Server as the only publicly accessible ABAP runtime environment. In some cases, the boundaries between ABAP developers and SAP Basis administrators are permeable, and each of the two groups of specialists has a basic knowledge of the other. As a rule, however, the competencies remain separate.
SYSTEM
Meanwhile, there are other ways to build consensus. But, for the most part, the following three options have proven effective as a consensus mechanism: 1) Proof of Work 2) Proof of Stake 3) Proof of Importance The differences are presented in another blog post. How do blocks form in a blockchain? Each block will build irrevocably on an older block. If you were to remove the block, you would also have to remove all blocks above it, which would destroy the entire chain of blocks. Because each new block also contains information from its predecessor block. This is very important for understanding the immutability of a blockchain. If you were to manipulate a block afterwards, you would have to adjust all the blocks that follow. The effort would be so infinitely large and expensive that such a manipulation can practically not be implemented. You can think of it as this. A blockchain arises from the cryptographically linked blocks (puzzles) full of transactions (puzzle pieces) and therefore cannot be changed without destroying the entire blockchain. For this reason, a blockchain is seen as an immutable transaction history agreed upon by a decentralised community. A blockchain is programmed to work with each miner on the longest part of the blockchain, as this is obviously the chain in which most of the work has been invested.
It is therefore not unusual for the authorisation allocations to be regularly reviewed in the course of a revision or by external auditors. This is a very laborious process with SAPS standard tools. In this scenario, an authorisation administrator would first have to manually assign each employee to a specific manager and determine their roles. After that, these roles should be exported from the system (for example, to an Excel file) and then submitted to the supervisor so that he can decide whether the role assignment is appropriate or not.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
For the SAP basis, this step is an inventory.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
Component Support Package One such support package (COP) applies to one software component (SAP_BASIS, SAP_HR, SAP_APPL, etc) and contains corrections for errors in the repository and in the dictionary in exactly this software component.
