CREATING NEW ROLES
Application layer: The application layer is the central component of the SAP ERP system and is therefore also referred to as the base system. All applications and calculations are executed here. The application layer communicates with both the database layer and the presentation layer. On the one hand, it requests data from the database layer, processes it and then passes it on to the presentation layer. On the other hand, data that is newly entered in the presentation layer is passed on to the database layer and stored there.
Hosting environments and third-party offerings have also contributed to these improvements. Public cloud environments such as Azure and AWS provide a layer of abstraction that eliminates the difficult task of maintaining the hardware that was required with SAP on-premises.
IT ROADMAP
The results of the tests can be documented so that the development can be considered over a period of time. This way, you will be aware of the revision and of the relevant issues before the examination.
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.
You can reduce the Queue selection. To do this, select the Support Package that should be the last in the queue. After that, the queue is recalculated. You can also start the recalculation explicitly with Queue. Note that you can only select Support Packages that are part of the software component you have selected (the mouse cursor will change its appearance accordingly). The support packages associated with the calculated queue are green. The highest support package of the previously selected software component is additionally marked with a green tick. The support packages that are no longer part of the queue are still visible in the list and can be selected again. If you want to set the queue for another software component, select New Component. Result You have defined a queue. Now insert the support packages in the queue [page 20]. Rules for the Queue The following rules apply to creating a Queue: If it is an FCS system, the first step is an FCS Support Package. If it is missing from the queue, it cannot be defined. Instead, you will receive an error message telling you the name of the missing FCS Support Package. You cannot insert an FCS support package in a non-FCS system (official state of delivery). Support packages for a selected component are queued in order. If support packages in the queue have connections to support packages of another component (further predecessor relationship, required CRT), the queue will be extended by additional support packages until all predecessor relationships are fulfilled. Note that the SAP Patch Manager takes into account the configuration of your SAP system and only adds support packages to the queue that can be inserted into your system.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
The connection to the personnel process automatically initiates the change process as soon as the master record is adjusted in the Human Resources Department.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
There is no doubt about the commands and their execution, because their true identity is veiled: Because of a simple disguise.
