Proactive and continuous optimization of system availability and performance
Significant changes have also been brought about by SAP's cloud strategy. For example, the latest products such as SAP HANA and SAP S/4HANA are available entirely as cloud solutions.

SAP Basis consists of three layers: a database layer, an application layer and a presentation layer. The database layer manages all the data of the SAP system in a database located on the database server and administered by a database management system (DBMS). The database supplies the connected SAP applications with the required data, data tables or system control tables. It also receives and stores new information generated by the user.
Schedule user adjustment as a job
If your system is already above SAP NetWeaver Release 7.0, then you must either import SAP Note 1731549 or a corresponding Support Package. Afterwards, when creating new users, it is no longer possible to assign user names that are only composed of variants of spaces or other invisible special characters. Important: Changes to already existing users with these names or their deletion option are not affected by this! The SAP Note also adds the customizing switch BNAME_RESTRICT, whereupon you can control yourself whether alternative spaces are allowed to appear in certain places in the user name. For this, the following values must be set in the customizing table PRGN_CUST: NO = The alternative spaces are still allowed in the user name. ALL = The character set is reduced to a defined range, excluding certain special characters because they have specific meanings in certain operating systems or databases. This predefined character set is: ABCDEFGHIJKLNMOPQRSTUVWXYZ_0123456789,;-§&()={[]}+#. FME = The letters F, M and E stand for Front, Middle and End. With an 'X' in this three-digit switch value you can now explicitly specify at which position in the user name no wide spaces and control characters may occur. All combinations are possible, e.g.: XME = None of these special characters may occur at the BEGINNING of the user name. XMX = In the user name none of these special characters may occur at the BEGINNING and at the END. FME = One of these special characters may occur at any position in the user name (this corresponds to the default setting, i.e. as if no entry was maintained in PRGN_CUST for the switch). SAP recommends the use of the value ALL.

Own development testing is very common in the quality system. Therefore, the customising/workbench developments must be transported to the appropriate system. It is highly recommended to use the order type "Transport of copies". This post explains why you should use this type of order and what you need to consider. Transporting copies - Why? All objects on the original transport order remain locked. Only the copies of the objects are transported to the next SAP system. If something goes wrong during transport, objects can easily be recollected or added. In addition, when copies are transported to the test system, no import is created in the production system. The import queue remains clean and clear. The problem with overtaking transports is eliminated. Transporting Copies - Creation To create a transport of copies, call the Transport Organiser through the transaction SE01. Check the Order Type "Transfers of Copies" and click View Create a new order (using the Document icon or F6 key). Then select the order type "Transport of copies". Then define a description and the destination system of the transport. Transport of copies - Add objects The transport order of the type "Transports of copies" was created. Now we want to add the objects of the original to be transported. Unfortunately, not all objects of an order can be copied directly. Therefore, it is important to take the objects task by task. A transport order can contain multiple tasks. Press CTRL+Y to highlight the task ID and then copy it by CTRL+C. Right-click on your order of the type "Transport of Copies" and select the Include objects option. Select the object list of an order and copy in the ID of the task that contains the objects to be transported. Confirm your input. All objects of the order are transferred to the transport of copies. You can then transport the objects to the test system using the normal transport procedure.

Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.

The miners then forward this information to other miners, who in turn do the same.

At that time, the data center infrastructure had to be upgraded before we could even proceed.
