E-Book SAP Basis
Planning & Design
Basis administrators often have basic ABAP knowledge, for example, and ABAP developers know the basics of SAP Basis. Nevertheless, the two fields of activity are usually organizationally separated in the company.
In the area of SAP Basic Administration there are many tasks that occur at long but irregular intervals, such as adjusting the system modifiability. As a result, the know-how is often lacking and it is quickly taken to the next search engine, where long and partially incomplete forum entries make finding the right approach even more difficult. For this reason, I will regularly record recurring tasks from the SAP basis Administration for you in simple tutorials. This blog post will start with the topic system modifiability and client control. If you want to jump directly to a step-by-step guide, just scroll down to the bottom, where I summarised everything once. System Modifiability - What Is It? The system modifiability allows you to set which objects of the repository and the client-independent customisation are modifiable or not. Repository objects can also be customised even further, with respect to the software component and the namespace. You can choose whether an object should be modifiable, restricted, or non-modifiable. In this context, restrictively modifiable means that repository objects can only be created as non-originals (small note: for packages the setting "restricted modifiable" and "modifiable" is identical in the function). Let us now turn to the direct approach to the changeover to system variability. Change system modifiability As a preparation, you should clarify how long the modifiability should take place in your system. I have learned from my clients that it is often desired to set the system to "changeable" for certain tasks from the specialist areas only temporarily. If you have organised this, call the transaction SE06 in the 000 client and click on the button "System Modification". If you do not have permissions for this transaction, you can try either the transaction SE03 —> System Modifiability or the transaction SE09 -> Jump -> Transport Organiser Tools -> System Modifiability (under "Administration"). The following screenshot shows the way across the SE03: Here you can change the desired namespaces and software components depending on your request.
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system.

The value for abap/heap_area_total can also be set dynamically in the lower pane. Once you click on the "Apply" button, the values are changed until the next reboot of your system. In addition, the report also provides ways to analyse the global extended global memory hidden behind the two buttons "EG Overview" and "EG Dump".
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.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".

So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
Here are some of the key differences:
