Technical structure
The application layer is the central component of the SAP R/3 system. This layer is therefore also referred to by SAP as the actual basis system. Within the layer there are application servers and a message server.
Presentation layer: The presentation layer is the top layer of the R/3 SAP Basis system and includes communication with the user. Here, the data is graphically prepared for the user on the terminal device by means of software components from the application programs of the application layer. The presentation layer represents the interface to the user (SAP GUI).
Migration of your SAP system
The lifecycle of an SAP system begins with the installation of the database platform. This is installed by an SAP Basis administrator and can consist of one of the following databases: HANA, Sybase, DB2, Oracle, MSSQL and MaxDB.
The 5 most common errors in SAP test management In this blog post I would like to discuss the 5 most common errors in SAP test management, which in my experience occur regularly in this area. I hope that with this I can give you some guidance so that you can avoid these mistakes. No test management Quite simple. You have complex SAP software in use or are just introducing a new module tailored to your company, but the test process plays a subordinate role and tests take place only sporadically and unstructured? Then you have already made the first mistake. To ensure high software quality, avoid hidden consequential error costs and consciously plan for a test period instead of the risk of time bottlenecks, a methodical approach should be planned. Too much testing If you have decided to introduce test management, you need to weigh up the resources required for this. A large amount of testing quickly pushes the cost-benefit ratio into the realm of inefficiency, because the time required for testing drives up costs. On the other hand, the test quality should of course be high. Therefore, a structured and comprehensive approach is of high importance. Basically, you should make sure that the costs for the test effort do not exceed the average of the consequential failure costs.
"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP base.
In the past, when we deployed SAP environments, we first had to work out detailed sizing and architecture and pass this on to the procurement team, who then ordered the systems and installed them in the data center.
For example, for the parameter abab/heap_area_dia, the RZ11 outputs: Description of the parameter abap/heap_area_dia in the RZ11 As you can see here, it is not a dynamic parameter.
