BRF Business Rule Framework
The application layer is the central component of the SAP R/3 system. This layer is therefore also referred to by SAP as the actual base system. Within the layer there are application servers and a message server.

Due to the technology diversity, including in the SAP product portfolio, the support by a single silo unit SAP basis is almost impossible. Likewise, there are many activities that are located for historical reasons in the SAP basis and in parallel in the non-SAP area. In this respect, the separation between SAP and Non-SAP must be examined and, if possible, eliminated by standardisation, integration and centralisation. For example, the issue of output management can be set up in a team that has knowledge in the SAP printing area as well as in the non-SAP printing area and has contact points in the SAP basis. From the SAP basis, tools must be made available to the non-SAP areas to support them in their work in the SAP environment.

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.

"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.

SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Here you can find some useful information about SAP Basis:

Error situations should be catchable: If they are non-critical elements, the following job can perhaps be started anyway.
