How are SAP modules and SAP Basis related?

Using various user, administration and monitoring tools, the SAP Basis system is controlled and managed by an administrator, who is thus responsible for its trouble-free operation. Many companies hand over these tasks to an external service provider.
The Advanced Memory thus contains mainly user contexts of different work processes, if these cannot be loaded completely into the roll area. Since the storage area is accessible for all work processes, the work processes can also access external user contexts that lie here. In addition, the Advanced Memory contains a global area where data can be stored independently of user contexts. The extended memory size is determined by the values of em/initial_size_MB and em/global_area_MB. The first parameter determines the size of the storage area in which user contexts can be stored, and the second determines the size of the global area. Parameters for Private Storage Last but not least, there is the private storage, which is only used when the user context of a work process has used up all the other storage areas available to it, i.e. its share of the extended memory and its rolling area. In this case, the workprocess goes into PRIV mode. A workprocess in private mode is bound to its current user context and will not become free for other tasks until the current request is completed. If it has used up all the private memory allocated to it, the workprocess will then be restarted and the memory released. This behaviour is controlled with the abap/heaplimit parameter. At times, the user context may exceed the value of abap/heaplimit. The parameters abap/heap_area_total, abap/heap_area_dia and abap/heap_area_nondia define an upper limit for private storage. The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total. The parameters abap/heap_area_dia and abap/heap_area_nondia, on the other hand, determine how much private storage a single (non-)dialogue workprocess can use.
SHARING OF THE SAP basis INTO A SINGLE APPLICATION AND INFRASTRUCTURE-RELATED LAYER
The Precalculation Server is a standalone application that allows you to generate and distribute Excel workbooks based on SAP BI data. Are you already using the Precalculation Server or would you like to take advantage of it in the future? I would be happy to explain the steps from installing the Precalculation Server to finally starting the instances on the target system so that you can use the Precalculation Server for your purposes. As a reader of our blog, you are certainly interested in tricks and tricks that will make your SAP system easier to handle. You may be familiar with the situation where you want to install a Precalculation Server yourself. Here you will learn how this task can be implemented in the SAP environment. Prerequisites For example, you need a Windows 7 or a Windows Server 2012 instance on which the Precalculation Server is installed to operate the Precalculation Server. Both 32 and 64-bit versions can be used. In addition, the machine requires a .NET installation to run the Precalculation Server in addition to a Microsoft Excel installation (32-bit version is essential). Download the installation files In advance, you should download the latest installation files from the official SAP website to the target computers. Cleanup Phase If you already have an existing installation on the system, the first thing you need to do is uninstall all items to use a clean host for the Precalculation Server. You can do this by calling the Windows Control Panel: The order must be followed according to the SAP documentation. Therefore, apply the following procedure for uninstallation, no installation of SAP should be visible anymore: Order: 1) SAP BW Precalculation Service 2) SAP Business Explorer 3) SAP GUI for Windows XY Note: During the installation and uninstallation of individual components, the progress bar status may be suspended at certain locations. This is not a cause for concern, but a normal behaviour. Often, it will stand at 92% or 95% for about 10 minutes.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: "www.sap-corner.de".
Various tools can be used for this purpose, which take over the maintenance, care, configuration and monitoring of the SAP system.
