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.
In every company with several SAP systems, there is a person responsible for the complete SAP Basis topics, usually there is even a separate department for this. This person ensures the trouble-free operation of the SAP systems. The person responsible also accompanies maintenance work or upgrades and intervenes in special situations, such as poor performance. Even for companies that hand over the operation of the SAP Basis to an external service provider, there are often still tasks from the environment of user and authorization management at this point.

Synchronisation of Dictionary Objects (SPDD): The developers can view the list of affected objects with the addition of Synchronise Modifications in the input image of the transaction SPAM. Synchronisation of Repository Objects (SPAU): Developers must call the transaction SPAU and then match it. Once the match is complete, developers must share the tasks and inform you. The comparison can be done in any client. Call SPAM. Select Insert Support Package Queue. You will be prompted again to perform the modification sync. Since it has already been completed, ignore the hint and select Next. SPAM completes the processing and returns the status.
In earlier product generations, databases from various third-party providers were used - primarily Oracle and Microsoft SQL. However, this has changed with the introduction of the new database generation SAP HANA.
