SAP Basis Consultant
The Basis system comprises a total of three layers (Figure 1):
The Technical Lead functions as the work package leader or sub-project manager within the SAP basis when the project is the focus of the SAP basis. The Technical Lead will become more important in the future as the SAP basis acts as a technology consultant and more projects and project activities are expected in the future. This role must be filled more and more often. Due to the increased demands, this role and the associated activities must be professionalised through training and further training.
Another important example is the reading permission for TemSe objects. The temporary files are often forgotten, because it is often not considered that cached (strictly) sensitive data, which is intended for only one user (owner), can be viewed by another user without permission - and across clients. The examples mentioned show us how important it is to carefully assign permissions for client-independent transactions. Download Transaction tables The transactions that enable the examples above, including certain expressions of the associated permission objects and our recommendations for them, can be found in the file "Critical cross-client permissions" for download. Other client-independent transactions are located in the Cross Clients TCODES file. The criticality of these transactions should be assessed according to the context. I recommend always being careful and keeping these transactions in mind.
Technical implementation and typical tools in the SAP Basis 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.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
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.
There are several ways to introduce and operate new applications.
