SAP performance optimization
The database layer is used to store all company data and consists of the database management system (DBMS) and the data itself. In every NetWeaver system there is a database server on which the SAP database is located. It provides all other applications with the necessary data. The data is not only data tables, but also applications, system control tables and user data. All basic components ensure that the user has fast and reliable access to this data.
SAP Basis or system administrators work with SAP Basis in a company. They are responsible for the correct installation, configuration and maintenance of the SAP application servers and applications, and in some companies also for the operating system and the SAP database if no administrators are available. Using SAP's own programming language ABAP, developers and programmers design SAP applications that run on the ABAP stack of the SAP NetWeaver Application Server as the only publicly accessible ABAP runtime environment. In some cases, the boundaries between ABAP developers and SAP Basis administrators are permeable, and each of the two groups of specialists has a basic knowledge of the other. As a rule, however, the competencies remain separate.

A dialogue box appears listing the installed software components with additional information. For more information on this dialogue, please refer to the Online Manual. SPAM: ABAP/Dynpro Generation Usage For performance reasons, the SPAM is set by default to prevent ABAP/Dynpro generation from occurring during the commit. The corresponding programmes are not generated until they are called. However, you can set the SPAM so that the generation takes place during the recording. It is quite possible that the SPAM will report errors during generation because, for example, a self-written or modified report is syntactically wrong and refers to an object that is being played over the cue. Often it is desirable to ignore the generation errors for the time being and to fix them after inserting them. Prerequisites to play Support Packages.
In addition to scanning and identifying the respective security vulnerabilities of a program, it is also possible to stop tasks that are to be transported to other SAP systems with security vulnerabilities in the further transport process This applies, for example, to the CHARM process based on SAP Solution Manager. This forces a programmer to securely check the programs he or she is responsible for according to the same security criteria. If a program then still has security problems, it can either be released via the dual control principle or returned for further processing. Do you know of any other solutions for improving ABAP code security or have you already gained experience with the products mentioned above? I look forward to your comments!
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
