Migration of SAP systems to HANA DB
Attendance of the course "SAP HANA - Introduction
There are several ways to introduce and operate new applications. As a company you have the choice between internal realisation and operation, outsourcing, cloud computing and so-called outtasking. In deciding on one of the above concepts, the SAP basis must be included for the evaluation of various technological and operational aspects, which offers the possibility to develop a sound decision. This decision has a significant impact on the future operation of SAP and the associated operating and maintenance costs. The recommendations listed here are intended to help you decide on other forms of service. Information on the recommendation can be found in the Master's thesis in chapters 7.8 and 9.6.

If you now want to change the permission data, you will be asked for values for the appropriate organisation levels. First enter a tilde (~) and define the value later in the derived roles. Maintain the permissions you want and then generate the master role. Adding the organisational level to the master role Step 2: Define derived roles Create derived roles Assign the master role After you have created the master role, it is the derived roles that are in the process. To do this, re-enter a suitable role name via the PFCG. In our example, it is called "findepartment_d01". For a better overview, it is usually useful to name and number the derivatives after the master roles. You can also define the roles according to a different scheme. After you have created the role, you must then enter the master role in the Derive from Role field in the Description tab. Confirm the Auto Enquiries. Customise the Organisation Levels Now go to the "Menu" tab. There you can see that the data from the master role was automatically copied. Since the role has not yet been generated, the Permissions tab is currently highlighted in red. Therefore, call "Change Permissions Data". The first call should automatically open a dialogue to maintain the organisational levels, as they are still empty. If this is not the case, or if you would like to adjust the organisational levels again in a later case, you can also access them via the button Ordende (see screenshot). If everything worked well, you can now see that the permissions were also automatically taken from the master role. If you generate the role, the permission tab will also appear green. Congratulations, you have successfully created a derived role! Repeat step 2 with the additional derivatives to adjust the organisation levels accordingly.
Copying SAP clients: Local, Remote, Import/Export
An important area of SAP Security is the analysis of the customer's own SAP programs, which are classically written in the proprietary SAP language ABAP. Here, too, as in all programming languages, security vulnerabilities can be programmed - whether consciously or unconsciously. However, the patterns of security vulnerabilities in ABAP code differ from those in Java stacks or Windows programs. The goal of these conventional programs is usually to either crash the program (buffer overflow) or to artificially execute the program's own code (code injection). Both is not possible in ABAP, since a crash of a process causes nothing else than the creation of an entry in the log database (Dump ST22) and a subsequent termination of the report with return to the menu starting point. So a direct manipulation as in other high level languages or servers is not possible. However, there are other manipulation possibilities.

The tasks described above, which occur at rather irregular intervals and involve a certain degree of complexity due to the lack of routine or process know-how, should be examined in order to determine whether they can be performed more efficiently by an external service provider. One question to be answered is whether it is necessary to keep the necessary knowledge in the company in order to be able to react faster than the external service provider. For example, for business critical systems. Security aspects should also be considered, as external persons gain access to the system. From now on, outtasking performance must be regularly monitored and checked for quality and documentation. A complete dependence on the external partner must not arise.
