CLOUDABILITY, OUTSOURCING AND OUTTASKING
SAP Basis is structured as a classic three-tier model. It contains the following components: Database layer (relational database management system) / Application layer (application server and message server) / Presentation layer (graphical user interface).
SAP Basis Operation manages the IT underlying the SAP system. In addition, the operation ensures the maintenance and availability of business processes. Various tools can be used for this purpose, which take over the maintenance, care, configuration and monitoring of the SAP system. Basic operation is the prerequisite for ensuring that the SAP system is fully operational and covers the business processes well.
The Advanced Memory thus contains mainly user contexts of different work processes, if these cannot be loaded completely into the roll area. Since the storage area is accessible for all work processes, the work processes can also access external user contexts that lie here. In addition, the Advanced Memory contains a global area where data can be stored independently of user contexts. The extended memory size is determined by the values of em/initial_size_MB and em/global_area_MB. The first parameter determines the size of the storage area in which user contexts can be stored, and the second determines the size of the global area. Parameters for Private Storage Last but not least, there is the private storage, which is only used when the user context of a work process has used up all the other storage areas available to it, i.e. its share of the extended memory and its rolling area. In this case, the workprocess goes into PRIV mode. A workprocess in private mode is bound to its current user context and will not become free for other tasks until the current request is completed. If it has used up all the private memory allocated to it, the workprocess will then be restarted and the memory released. This behaviour is controlled with the abap/heaplimit parameter. At times, the user context may exceed the value of abap/heaplimit. The parameters abap/heap_area_total, abap/heap_area_dia and abap/heap_area_nondia define an upper limit for private storage. The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total. The parameters abap/heap_area_dia and abap/heap_area_nondia, on the other hand, determine how much private storage a single (non-)dialogue workprocess can use.
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.
Automation of processes In an IDM, IT business processes, creating, modifying and deleting a user are defined centrally by means of a unique set of rules. All the necessary steps are then completed using automated workflows. User administration no longer has to be administered separately for each system, but only in a single point of administration. Data Consistency Employee data is created only once in a leading system in an IDM architecture. All attached systems use this data in their user management on demand. In a change of department or a new activity, permissions are automatically adjusted. Security and Documentation In a centralised user administration, users can be locked down efficiently on all systems or access rights can be changed. The connection to the personnel process automatically initiates the change process as soon as the master record is adjusted in the Human Resources Department. Documentation solutions can also be used to archive all processes without any gaps. This creates transparency which also facilitates the detection of a functioning and secure authorisation concept during audit tests. Requirements for IDM systems People get electronic identity attributes describe the role of the person Quality requirements Reliability: Abuse prevention Readability: Documentation and logging Failover: Back-up systems in compliance with legal requirements Data Protection Act What should be taken into account in application processes? When implementing an IDM and also in the day-to-day operation of an IDM, there are certain things that should be taken into account when applying. I have summarised the most important points in the form of a checklist.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
