Why does your company need an SAP Basis team?
SUGR Maintain user groups
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.
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.
CREATING NEW ROLES
If you look at everything I've described up front in its entirety, it quickly becomes clear which direction things are headed: the SAP basis will increasingly move toward an SRE-centric environment over the next decade. This is what the future of SAP looks like, and I look forward to an exciting journey.
Within the framework of an innovation team or test laboratory to be created, it is necessary to admit ideas outside of the SAP basis or to consciously use other sources of ideas within and outside the company. These may include business units, external service providers, universities or series of lectures on specific topics.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
This step is less important for the SAP basis.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
