The comprehensive analysis provides the pattern and roadmap for the next steps. This also includes the right sizing, the selection of the monitoring concept and the appropriate deployment model, i.e. on-premise, cloud or hybrid cloud. Only with this planning can you ultimately achieve the desired goal - with transparent costs.

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.

The marketing mix model is suitable for creating a marketing concept. This is usually divided into four pillars - the four Ps. These are Product, Price, Place and Promotion. In the case of services, this is often accompanied by the aspect of personnel policy. Although the marketing mix model is aimed at the external distribution of products and services, aspects of it can also be applied to an internal marketing of the SAP basis. For the design of the respective areas of the marketing mix, it is recommended to use a guide to develop a marketing concept. STEP 1: DEFINITION OF PERFORMANCE This step deals with the description of the services to be offered. Similarly, this step provides a categorisation of the type of service. These include, for example, the levels of secondary or primary service. With respect to the SAP basis, this step is concerned with product portfolio analysis and the creation of IT products and a product catalogue. STEP 2: OWN RESOURCES Subsequently, a determination of one's resources takes place. That is, it identifies the resources that are available and that can be used and the resources that need to be developed. Resources are people, objects, systems, knowledge, and funds. For the SAP basis, this step is an inventory. STEP 3: DETERMINATION OF THE OBJECTIVES The mission and vision of service providers will be determined in the framework of the setting of the objectives. It also sets measurable targets for the next three years.

SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page:

Protect: CodeProfiler for ABAP protects the SAP system from internal and external attacks from the first day of deployment. The ABAP firewall can be set up within a very short time and immediately checks every new transport request when it is released. Optimize: The audit function of CodeProfiler for ABAP specifically determines which programs are most threatened and should therefore be cleaned up first. In the long term, CodeProfiler for ABAP supports the automated correction of all findings and thus enables the timely closure of security gaps in all programs.

Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".

Strategically, completely self-hosted SAP systems are becoming rarer and the proportion of customers using an SAP system from the cloud is increasing.

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.

In Unicode systems, "alternative" spaces, so-called "wide spaces", can be used in addition to the normal space character (hexadecimal value 20).
