Usage
The Expert Team Lead leads a group of specialists, e.g. a group of SMEs or a specific technical area such as a group of operators. For example, this role can lead and steer a virtual group of experts with the participation of other IT departments on the topic of print management. The role serves as the interface and contact of the SAP basis to other specialist areas such as memory management or operating systems. In cooperation with other IT departments, the Technical Team Lead leads expert groups. These expert groups are usually virtually organised and their existence limited in time. The role of the Technical Lead functions as (partial) project leader for topics and projects of particular importance to the SAP basis. He takes care of all the activities involved in project management and control.
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.

As an SAP Basis administrator, you are faced with the challenge of balancing acute daily business and recurring routine tasks. As the complexity of the systems and the interdependencies tend to increase, the challenges are great and the requirements are growing. Daily and at the same time business-critical routine tasks are SAP job control and regular data backups. Automating these tasks can free up time for the day-to-day business of maintenance, servicing, support and troubleshooting. Clear monitoring and alerting in the event of an error help to maintain operational reliability and meet corporate compliance requirements.
Understanding the structure and functionality of the system is especially important for IT administration. It's not for nothing that "SAP Basis Administrator" is a career field in its own right. Instead of data and application development, the focus here is on providing the software environment on which the company's tools are created. SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
If your SAP employees are absent due to illness or vacation, there may be no equivalent replacement available.
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
Either temporary programme calls are blocked that are actually desired or enormously large gateway logs must be analysed.
