Update of the SAP system to newer versions
Why does a company need an SAP Basis department? [Using our company as an example]
The database layer is where all of a company's data is stored. In essence, it consists of a database management system (DBMS for short) and the data itself.
The operator is now responsible for ensuring smooth and safe operation in the SAP environment. It has a basic understanding of the infrastructure and is well connected within the IT departments. For his daily work he uses suitable tools (e.g. monitoring tools), in which he is trained and trained. In the future, the focus will be on reactive activities such as monitoring systems and processing notifications. The operator acts as a customer of SME-expression standardisation and automation as well as the SME-expression-solution manager. Also, the operational aspects of this role are suitable for outsourcing. However, the accountable parts remain in the company.

The SAP Basis is responsible for the smooth operation of the programmes in the SAP system. It acts as an operating system for R/3 and subsequent releases including S/4HANA. Each operating system provides an environment in which programmes can run, such as MS Office on Microsoft Windows. Likewise, the SAP base system with the NetWeaver and HANA platform offers an environment in which the SAP programmes can run. In this context, the NetWeaver platform itself relies on server operating systems such as Windows and Linux.
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.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
If the user does not have permission to execute the transaction SPAM or the current queue has not yet been confirmed, the transaction stops SPAM with a message to that effect.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
Therefore, SAP Basis is an important core of any SAP infrastructure and is required in both previous versions such as R/3, as well as current versions such as S/4HANA 2021.
