The prerequisite for employment is a relevant university degree (bachelor's degree, FH diploma) preferably in computer science, business informatics, mathematics or a scientific discipline as well as at least three years of practical experience. Ideally, you also have a completed scientific university education (master's degree, university diploma).
By correctly assessing your own applications for suitability for operation with an external service provider or in the cloud, the enterprise risk of the chosen service form is minimised. Also, possible weak points or aspects that require special attention are known and can be dealt with proactively. A negative consequence during the operational operation can be largely excluded.

It is possible to specify a trace level for each rule in the ACL file to monitor each communication channel individually. It can be used with SNC without any further configuration. The use of the file is controlled by the gw/acl_file parameter by simply setting it to the appropriate file name. Use of external programmes If an external programme wants to communicate with your SAP system, it must first register at the gateway. The programmes which this is approved are controlled by the reginfo ACL file. This defines rules that allow or prohibit certain programmes. The syntax of the file allows you to define not only the name of the programme, but also the host on which the programme runs and hosts that can use and exit the programme. The gw/reg_info parameter must be set to use this file. In addition, there is the ACL file secinfo, which allows to configure which users can start an external programme. This defines rules that allow certain usernames from the SAP system to use certain external programmes. In addition, you can also define the hosts on which these programmes will run. For example, it is possible to allow a user to run the programme "BSP" on the host "XYZ", but not on the host "ABC". This file is controlled by the gw/sec_info parameter. Using the gateway as a proxy Since the gateway of your SAP system can also serve as a proxy server, the prxyinfo ACLDatei should also be activated via the gw/prxy_info parameter. Suppose you have 3 SAP systems in your network: SRC, TRG and PRX. If SRC cannot communicate directly with TRG, but both with PRX it would be possible to use the gateway of the PRX system as a proxy server, i.e. to communicate via it. So, in order to prevent this from happening to everyone, this property should be urgently restricted. As with the other ACL files, rules are defined which hosts can communicate with which hosts via the gateway. The syntax of the different ACL files may vary depending on the release level. It is therefore advisable to read them in the appropriate SAP documentation before activating the ACL files. You can also find more support for using ACL files in the SAP Community Wiki.
Presentation layer: The presentation layer is the interface to the users. With the help of SAP GUI, the data is graphically prepared here and made available to the user on the screen. Furthermore, the data newly collected here is passed on to the application programs of the application layer.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
Because each new block also contains information from its predecessor block.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
A degree in computer science is usually a prerequisite and is now almost compulsory.
