SAP Basis - Administration of SAP system landscapes
SICK SAP Installation Check
SAP Basis Operation is responsible for ensuring the technical functionality of an SAP system. It includes all the technical components mentioned above. These are used to perform the following tasks:
The decision to outsource a task or service should be taken not only in terms of cost, but also by assessing the competitive differentiation and strategic importance. Characteristics for describing the costs are the specificity of the task and the embossing by unit cost degression, i.e. decreasing costs with increasing number of tasks or performance. Of strategic importance are, in particular, those tasks and services which are difficult to imitate by competing companies. Figure 4 compares the strategic importance and cost advantages in order to arrive at fundamentally valid statements regarding the usefulness of outsourcing for certain IT tasks and services. In addition to this, as already discussed by Recommendation [A2], it is then worthwhile to establish a catalogue of criteria for evaluating and looking in detail at certain characteristics of the application or services. An exemplary catalogue of criteria can be found in chapter 9.6 of the Master thesis. Figure 4: IT Outsourcing Decision Matrix THE DECISION TO OUTSOURCE A TASK OR PERFORMANCE SHOULD BE MADE NOT ONLY IN TERMS OF COSTS BUT ALSO BY ASSESSING COMPETITION DIFFERENTIATION AND STRATEGIC IMPORTANCE.

In order for Fiori applications to be displayed according to the calling users, appropriate Fiori permissions must be maintained in the PFCG. There are several points to consider. This article discusses the permissions required to launch a Fiori application. In addition, a short explanation is given, how the displayed tiles can be configured in the Fiori launchpad via reels. To run Fiori applications from the launchpad and the permission queries defined in the OData services, the corresponding Fiori permission objects must also be maintained in the PFCG. Here the start permissions for the application's OData service in the backend system as well as permission objects are relevant for the business logic of the OData services used in the application. In general, it is important to know that if Fiori is implemented correctly, permissions must be maintained in the front-end server (call Launchpad, start the tile, etc.) as well as permissions in the back-end server (call the OData services from the backend). This article explains this in more detail.
New risks in SAP HANA: In addition to the known risks, there are also new risks from the use of SAP HANA. A very good example are frequently used web applications that represent something new in the SAP area. In contrast to an SAP ERP system, HANA systems consist mainly of web applications, which were considered optional in the previous versions. These web applications can be found by various search engines on the Internet. This also applies to SAP Portal or Netweaver. There are URL schemes that help locate the system. This also applies to other SAP systems that use Web applications. This makes the new technology vulnerable to typical web attacks. SQL Injection, ABAP Code Injection, or XSS are all included. All risks known for a normal SAP system also apply to a SAP-HANA system. The data is stored unencrypted in RAM. Only then does the system gain this speed advantage. This results in risks such as a read-out by memory scraping malware. These pick up data in memory. Encryption costs performance, so it is not used by default. Especially during a migration HANA runs in a parallel system, therefore at least one new system comes to your landscape. Also note: HANA has its own tools and settings that need to be known and configured. The bottom line is that the system simply needs more attention when operating. Many settings often result in more errors. Three - points - HANA Security Plan 1) Roles and permissions In a previous SAP system, roles and permissions are certainly one of the main pillars of a secure system. Roles and permissions work differently in a HANA system. There are two types of users: 1) Default (limited): With this type of user, there are different access methods to the database. For example, the JDBC or HTTP technologies are used to give two examples.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
In more complex system environments, thousands, if not tens of thousands, of SAP jobs can run per day.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
