What are the different areas when working with SAP systems?
Installation
So-called Access Control Lists (ACL) offer a good possibility to secure your gateway in order to exclude unwanted external accesses to the database of the application server. 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. The reginfo file controls the registration of external programs on the gateway, which means that rules can be defined that allow or prohibit programs. With the help of the file secinfo you can define which users are allowed to start an external program. To be able to use these files, you must set the parameters gw/reg_info and gw/sec_info (transaction RZ11). For more information, refer to SAP Note 1408081.
A Conflict Resolution Transport (CRT) is used only for add-ons, such as IS-IS or IS-OIL. It is used to eliminate conflicts that may arise between the different support packages and an add-on. Note that a CRT that applies to an add-on release also resolves all conflicts with previous releases of that add-on. In addition, a CRT may include other corrections for the corresponding add-on. A CRT can therefore always be a special add-on support package. Settings for SPAM With Additional Settings, you can access a dialogue box where you can specify general settings for the SAP Patch Manager (SPAM). These settings affect the behaviour of downloading and loading support packages of the different types equally. SPAM updates are an exception; certain settings are specified for these. You can toggle the following properties on and off: Transmission Monitor If you enable the Transmission Monitor, you can monitor the download of the support packages from the SAPNet - R/3 frontend with a graphical monitor. Otherwise, you will only get a progress bar. Scenario Choosing the scenario determines which actions should be performed while the Support Packages are being played in. The default scenario is used to fully deploy support packages; All steps are performed. The test scenario allows you to determine whether a modification match is required or whether conflicts occur that should be resolved before the support packages are loaded. The test scenario does not import data and objects into your SAP system. There is no test scenario for SPAM updates. The choice is ignored when a SPAM update is introduced. Rebuild data files You can specify whether the data files from the EPS packages will be reunzipped each time you try to play. In principle, this is the case.
Application of SNOTE and elimination of errors
If you look at everything I've described up front in its entirety, it quickly becomes clear which direction things are headed: the SAP basis will increasingly move toward an SRE-centric environment over the next decade. This is what the future of SAP looks like, and I look forward to an exciting journey.
On www.sap-corner.de you will also find useful information about SAP basis.
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 simpler option is to output the transactions used by the expert as a list and to obtain an overview of the task areas. The function block SWNC_COLLECTOR_GET_AGGREGATES is very suitable for exporting the used transactions in a list. As an alternative, one can directly use the workload monitor in the transaction code ST03N.
"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP basis.
It is therefore not unusual for the authorisation allocations to be regularly reviewed in the course of a revision or by external auditors.
The establishment of Software-Defined Data Centres or IaaS are the key to further flexibility and standardisation of SAP technology infrastructure.
