SAP Basis Introduction and R3 Architecture Overview (in English)
The database layer
In order to escape the checks carried out by the iris scanners and ultimately his own arrest, a doctor illegally reuses his eyes and acts under a new identity. With the help of the new eyes he finally succeeds in entering the secured area of the "Precogs" and he can begin his investigation. Through this "biohacking" he not only deceives the biometric security systems - he compromises the highest police control system. All stories!? "Great stories!" think now. But: No one will ever fall for a simple trim. And anyway: Biometric security systems and eye transplantation? It's not for nothing a science fiction movie! What does this have to do with RFC security? All right, I can understand your doubts. But how do you like the following story, for example? RFC Security and the Art of Identity Change Germany, everywhere, 2017: Johannes Voigt has been a medium-sized company employee for several years. He is considered a reliable and conscientious developer from the IT department. In fact, he is increasingly unfairly treated. He decides that he no longer wants to carry his frustration with him.
It is of great importance to keep the knowledge of SAP Basis experts in the company transparent. One possibility is of course to "look over the shoulder" or to ask the expert directly. However, this is very time-consuming and puts a strain on the expert himself.
This option is useful if several transactions are to be checked simultaneously for their existing assignment to a particular user. This variant must first identify all roles that have already been assigned to the user. This is done in the transaction SE16N by entering the table AGR_USERS. In addition, the limit of the maximum hit number can be set in this image. The user concerned must now be entered here. Furthermore, the output should be limited to the roles only. After the query is executed, all the roles assigned to the previously entered user are displayed. These are now completely marked and copied. Then in the transaction SE16N a step back is taken and this time the table AGR_1251 is selected. Now all the roles that have been copied previously are inserted here. In addition, the object S_TCODE and the transactions to be searched for are filtered. Warning: When entering transaction codes, be sure to be case-sensitive! At this point, the output can also be limited to the roles and object values (in this case, the transactions). After the query is executed, the transactions entered will now show those that the user can already perform. In addition, the role assigned to the transaction is shown. In conclusion, the SUIM is only partially suitable for identifying certain transactions with user assignment. Although the search using the S_TCODE permission object also allows you to view multiple transactions. However, since the result is missing the assignment of transactions considered to roles, the SUIM transaction can only be usefully used to check a single transaction for its existing assignment to a particular user.
SAP, as one of the world's leading software providers with over 100,000 employees, represents a central component of their system landscape for many companies. Thanks to the many different modules, such as "Finance" and "Human Capital Management", as well as the wide range of customization options, a broad field of professions and possible areas of focus has opened up here in almost 50 years.
"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP base.
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.
The new roles also provide increased visibility and participation in company decisions.
