The typical tasks of system support and administration of an SAP landscape, regardless of whether it is 2-tier or multi-level, include the following
SM50 Work process
In this case, the term stands for the basic administration of SAP systems. In this context, responsible employees perform a number of classic tasks.
This possibility is particularly advantageous when it is a new topic and there is not yet a lot of know-how in the company. Instead of buying an expensive coach to teach employees the basics of a new topic, this means that the knowledge can be made available more cheaply and in a longer term, for example, through an online course.

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.
In the area of SAP Basis it is necessary to make temporary changes in the security settings of the clients and systems in the course of system updates. You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, as well as client-independent customizing is allowed.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
With the help of the ACL files reginfo and secinfo an access control can be implemented, in which allowed as well as forbidden communication partners can be defined.
Poor test preparation The relevant processes have been defined, the test plans have been created and the test period has begun - so can testing begin? Not always.
