Parameters in the SAP create a high degree of flexibility. Profiles can be used to configure the system for almost any purpose. But with such a large number of parameters one quickly loses an overview of the influence of each parameter. For storage management alone, there are 20 different parameters that can be changed at different points in the SAP system. This article brings order to the mess and explains the most important parameters. There are three types of memory in the SAP system for a work process: ・ Roll Area - Local Memory Area for a Work Process ・ Extended Memory - Global Memory Area for All Work Processes ・ Private Storage /Dynamic Memory (Private Memory/Heap Memory) - Private Memory Overview of SAP System Memory Regions Parameters for the Rolling Range When a user starts a programme, a role area is created for that programme instance through a workprocess. The user context is stored in this memory area. The size of the roll area for a work process is determined by the ztta/roll_first parameter. If the storage area is not sufficient, a portion of the Advanced Memory will be allocated for the user context, the size of which will be determined by ztta/roll_extension, ztta/roll_extension_dia, and ztta/roll_extension_nondia. The latter two override ztta/roll_extension if used and offer the possibility to set different quotas for dialogue and non-dialogue work processes.

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.

Migrations occur, for example, when a customer decides to host his systems at Rödl & Partner and the SAP systems therefore have to be migrated from in-house operation or from the original hosting provider to our data center. Also in the course of a conversion to S/4HANA, the data is migrated from the original database type to an SAP HANA database. This is also done with the tool "SUM" (Software Update Manager) via the so-called "DMO" (Database Migration Option).

On the one hand, staff clerks (or other personnel officials) should be able to carry out their important work. On the other hand, the protection of personal data of one's own employees is one of the most important tasks of the authorisation system. Any mistake in this area can cause the company's data protection officers to wring their hands over their heads. For this reason, tools are currently being developed to provide security and visibility in the HR permissions area. The basic idea is a clear overview that shows which data certain users in the SAP system can access. Based on this, automatic checks can be developed, which run in the background and regularly check whether critical gaps have been created by changes to the permissions in the HR area. The use of such a tool can create more security, especially in the HR authorisation environment. In addition, the possibility of the overview function is very pleasant and relieving for all involved. Read more This blog post is intended to show what is already possible in the field of Security Automation. The topic will accompany us more and more in the SAP area in the next few years. Therefore, it is recommended to start thinking about how your company is prepared for security automation. If you are interested in setting up and preparing a company outside the security area, I can recommend the book 'Consulting Y' by Ferdinando Piumelli (Managing Director of mindsquare GmbH). In this book, Mr. Piumelli describes his observations and experiences of digital transformation as a strategy consultant for leading DAX30 companies. In doing so, he is focusing on the near future, which, in the spirit of the digital revolution, will have a major impact on the world's large companies and economy.

Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.

The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
