SAP Basis is characterized by a three-layer model and consists of the following layers:
OAC2 Change document types
For the authorisation requirement of a user, the transactions with user assignment already awarded should be determined accordingly, in order to be able to exclude them when selecting a suitable role. How does this work? There are various ways to identify specific user-assigned transactions, with varying degrees of result. The following article presents two variants. The first section first describes how to use SUIM to address the problem and what problems are encountered. It then explains how the task can be solved by using the transaction SE16N. As in the previous blog post Identifying all transactions of multiple roles, the roles Test_Schmidt1 and Test_Schmidt2 are used for this. Two of the transactions MM01, MM02, MM03 and MM04 were assigned to these roles in different ways. In the Test_Schmidt1 role, the transactions MM01 and MM02 were entered in the Role menu. In the Test_Schmidt2 role, the transaction MM03 was maintained in the menu of the role, but the transaction MM04 was maintained only in the S_TCODE permission object of the role. Both roles have been assigned to the user SCHMIDT_TEST. Identification of certain transactions with user assignment using SUIM This option is useful if only one transaction is to be checked for its existing assignment to a particular user. The audit is carried out here by means of the transaction SUIM. For this purpose, the variant "Roles according to complex selection criteria" has to be executed in the SUIM. After activating the option "With valid assignment of", the corresponding user and the transaction to be checked will be entered here. It is also recommended to hide the display of the collection roles in the search results.
The database layer manages all data in the R/3 System. It contains the database management system (DBMS) and the actual data.

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.
Due to the variety of tasks and the high complexity, I find my job extremely exciting. There are very many constellations of SAP systems and databases. Each installation, migration and update brings new aspects and challenges. It is precisely these challenges that are important to me, so that I can continue to learn and develop professionally on a daily basis.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
In the ERP environment, SAP has created a separate module for each business task area over the course of time.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
Since SPAM runs within the SAP system, you do not need to know the operating system to handle the transaction.
