A role concept according to best practice protects you from potential attacks within your SAP landscape. However, to protect your system from unauthorized access via the network, the SAP Gateway must be configured correctly. It enables the use of external programs via interfaces or the call of ABAP programs and serves as a technical component of the application server, which manages the communication of all RFC-based functions.
If this parameter is exceeded by a process, the query is cancelled before it could be executed. Both parameters are limited by the parameter abap/heap_area_total. Of course, there are several other storage parameters that would exceed the scope of this article. You can read their function in the SAP documentation.

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.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
As an interface to the user, the presentation layer contains software components (the SAP GUI) by means of which the user is presented with the application. During its runtime, an SAP GUI component is always permanently linked to a user logon to the NetWeaver AS ABAP.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
He or she maintains the SAP applications and is also responsible for their further development.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
