Implentation of the Security Audit Log (SAL)
SAP Basis consists of three layers: a database layer, an application layer and a presentation layer. The database layer manages all the data of the SAP system in a database located on the database server and administered by a database management system (DBMS). The database supplies the connected SAP applications with the required data, data tables or system control tables. It also receives and stores new information generated by the user.

Whenever you find a red traffic light on the Roles tab in the user master in SU01 - or a yellow traffic light on the Users tab in PFCG, you can usually solve the problem with a simple user synchronization. The fact that such a user adjustment is necessary can have several reasons. Among others: after a role transport to / when assigning users to roles via PFCG after restricting the validity of roles to users when roles are assigned indirectly via organizational management. Users usually notice the problem of a user comparison that has not been carried out quite quickly: Authorizations are missing, although at first glance they are available in the assigned authorization roles. This is because a user is assigned the correct authorization role - but the profile associated with the role is not up to date.

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.

What do RFC interfaces and RFC security have to do with the play "Hauptmann von Köpenick" and the science fiction film "Minority Report"? Probably more than you like! RFC security and theatre?! Germany, Berlin, 1906: The 46-year-old cobbler Wilhelm Voigt dreams of returning to a normal life. After various convictions and many prison stays, he lives on the margins of society. It's not just the money he lacks. Above all, the lack of access to his social system makes him. In view of his impasse, he opts for a drastic measure. The excluded shoemaker pulls off and grates off several junk dealers to assemble a military uniform gradually. A few days later, he slips into the same disguise, successfully changes his identity and then swings through Berlin as Captain von Köpenick. He commandeers soldiers, storms the town hall and even detains the mayor. There is no doubt about the commands and their execution, because their true identity is veiled: Because of a simple disguise. A disguise that gives him all the necessary permissions he needs for his scam. At the end of the day, Wilhelm Voigt successfully compromised the Berlin government. RFC Security and Science Fiction?! USA, Washington, DC, 2054: The Washington police have long since stopped investigating murders: It prevents the killings right in advance. For this purpose, so-called "precogs" are used, which use precognition to predict and report murders in visions before they happen. At the same time, the government uses a system of public scanners that can identify all citizens clearly at any time by iris detection. One day, when policeman John Anderton himself appears as the culprit in a vision of the "Precogs," he flees the police building and decides to find out why.

With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

For example, for the parameter abab/heap_area_dia, the RZ11 outputs: Description of the parameter abap/heap_area_dia in the RZ11 As you can see here, it is not a dynamic parameter.

SAP Basis is the cornerstone of your SAP system and failures can lead to significant and annoying problems.

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.
