Conclusion and outlook
PFCG Role maintenance
ABAP is therefore the tool of the trade for SAP developers. ABAP programs are executed on an SAP NetWeaver application server, which in turn is operated by SAP Basis employees.
If all financial and sales activities as well as production, logistics and the personnel administrators run via one system, measures must be taken to ensure reliable functioning on the one hand and to protect the system internally and externally on the other. Due to the long history, the increased availability requirements often do not match the actual protection measures, so that security risks often arise at this point.
SAP Basis - operation, structure and definition
SAP Basis ensures smooth operation of the SAP Basis system. The SAP Basis system is a kind of operating system of the R/3 system or SAP ERP. It includes three layers: database, application and presentation. In addition, Basis includes many SAP middleware programs and administration tools. With Basis SAP applications can be used compatible and independent of operating system and database and can be enriched with the necessary data.
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.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
The main task of the SAP basis is to support new business models by implementing the strategy and to show how much technical and financial effort and benefit is generated.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
