The SAP NetWeaver Application Server Add-on for Code Vulnerability Analysis tool, also known as Code Vulnearability Analyzer (CVA), is a tool that performs a static analysis of user-defined ABAP source code to detect possible security risks. The tool is available in the NetWeaver ABAP stack and is based on versions from: 7.0 NetWeaver: in EHP2 SP 14 or higher / 7.0 NetWeaver: in EHP3 SP 09 or higher / 7.3 NetWeaver: in EHP1 SP 09 or higher / 7.4 NetWeaver: in SP05 or higher To use the CVA tool, the execution of system-wide security controls must be enabled with the RSLIN_SEC_LICENSE_SETUP report. Afterwards, the security checks are available in standard ABAP code checking tools such as ABAP Test Cockpit (ATC) or Code Inspector (SCI). The option of these checks is usually referred to as "security analysis in extended program check". Note that the use of the security check feature for custom code separation is licensed and incurs additional costs. The older program that has been around for years is Virtual Forge's "Code Profiler". It is one of the first products in this segment of SAP security and was used by SAP itself for many years. It is very comprehensive and is also able to track individual variables across the entire control flow. This leads to very precise statements and a reduction of false positives.

Soft skills also play an important role in this profession. In everyday life, communication skills are in demand, because SAP administrators are often in close contact with customers and have to respond to their wishes and questions. They also need to be able to work in a structured manner and find creative solutions and decisions. In order not to lose touch, continuous training in this area is advisable.

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.

Following the recommendation of dividing the SAP basis into an application-orientated and infrastructure-related SAP basis [A4], Figure 3 shows a possible presentation form. The SAP-Basis interface function is structured into a SAP basis, which is close to the application and is responsible for coordination and communication with vertical and higher IT specialist and business areas, and a SAP basis close to the infrastructure. The infrastructure-related SAP basis in turn serves as the link between the application-orientated SAP basis and the infrastructure levels. Subject Matter Experts will perform the link task again. In the application-orientated SAP basis, in turn, technology architects are more likely to be placed. The innovation activity or innovation team aspect of the SAP basis is placed at the level of the SAP basis, which is close to the application, because the existing capabilities allow it to assume a leading, also coordinating role and acquire expertise both by adding the SAP basis near the infrastructure and the downstream IT departments.

With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

Change system modifiability As a preparation, you should clarify how long the modifiability should take place in your system.

STEP 2: OWN RESOURCES Subsequently, a determination of one's resources takes place.
