SAP Basis Introduction and R3 Architecture Overview (in English)
Using profile parameters, we can configure everything in the SAP system. Some parameters are dynamically modifiable, which means that they can be changed without restarting the system. However, these changes are not permanent, i.e. after a system restart, the pre-set profile parameters are used again. Other parameters, however, are static, i.e. only with a restart and only permanently modifiable. Most profile parameters for memory allocation are actually static. However, there is the possibility to adapt it dynamically with the report RSMEMORY. Read how to find out if a parameter is static or dynamic and how to use the RSMEMORY report to dynamically adjust the memory allocation parameters. RZ11 - Maintenance of profile parameters The transaction RZ10 gives us information about profiles, which in turn contain different profile parameters. In the transaction RZ11, however, it is possible to view information about individual parameters, provided that you know their name. As you can read in our Memory Parameter Post, the following 5 parameters are particularly important for memory management: abap/heap_area_total abap/heap_area_dia abap/heap_area_nondia ztta/roll_extension_dia ztta/roll_extension_nondia If you don't know exactly what a parameter might be called, it's worth using the F4 help here. 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. Now it is rather sorry if you want to test whether there is enough memory available to restart the system again and again. For this purpose, there is the RSMEMORY report. RSMEMORY - Test your memory allocation strategy Report RSMEMORY Report View No documentation or value help available here, but SAP documentation tells you how to use the report. This first distinguishes between dialogue and non-dialogue work processes. That is, in the first area you can set Extended Memory (Storage Class 1) and Heap Memory (Storage Class 2) for Dialogue Workprocesses, and in the second area you can set it for non-dialogue workprocesses.
It is of great importance to keep the knowledge of SAP Basis experts in the company transparent. One possibility is of course to "look over the shoulder" or to ask the expert directly. However, this is very time-consuming and puts a strain on the expert himself.
The website www.sap-corner.de offers many useful information about SAP basis.

Reachable at any time: Your competent contact person is available at all times. If you operate SAP Basis Support in-house, personnel bottlenecks may occur. If your SAP employees are absent due to illness or vacation, there may be no equivalent replacement available.
People tend to forget how important this element of the architecture is. The setup involved often proves to be especially important for companies looking to implement the SAP system for the first time.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
It must be specified which users can get special rights.
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.
Likewise, the SAP basis should serve as a sparring partner for individuals and boards (such as enterprise architects) that significantly influence the strategy.
