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.
But when it comes to the intricacies of large SAP environments, Ansible quickly reaches its limits. If you want to use Ansible to implement simple automations - for example, starting and stopping SAP environments - you have to put up with a lot of manual effort and complicated scripts.

SAP Basis administration is distinct from other roles such as ABAP developers and consultants who handle architecture. In many companies, the boundaries between administration and development are blurred. Admins may therefore also be involved in the planning and development of the system.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
