SCOPE OF SERVICES OF SAP BASIS
R/3 SAP Basis System Structure
In transaction PFUD (see image above), you can perform the user match manually for all roles (or selected roles). You can choose between the matchup types Profile Matchup, Matchup of Indirect Assignments from Composite Roles, and Matchup HR Organizational Management. According to SAP documentation, the matchups differ as follows: Profile Matchup: "The program compares the currently valid user assignments of the selected single roles with the assignments of the associated generated profiles and makes any necessary adjustments to the profile assignments. Matching indirect assignments from composite roles: User assignments to composite roles result in indirect assignments for the single roles contained in the composite role. This match type matches the indirect assignments of the selected single roles to the user assignments of all composite roles that contain the single roles. If the selection set contains composite roles, the comparison takes place for all single roles contained in it. HR Organizational Management comparison: This comparison type updates the indirect assignments of all selected single and composite roles that are linked to elements of HR Organizational Management. The HR adjustment is inactive and cannot be selected if no active plan version exists or if a global deactivation has been made by setting the Customizing switch HR_ORG_ACTIVE = NO in table PRGN_CUST. Furthermore, the option "Perform cleanup" is interesting, which can be selected independently of the three adjustment types and does not refer to the role selection. The Perform Cleanup function can be used to remove residual data that resulted from incomplete deletion of roles and the associated generated profiles.
This is the heart of the SAP system. In the classic three-tier model, this would be the logic or control layer. One or more application servers host the necessary services for the various applications at this layer. These application servers provide all the services required by the SAP applications. In theory, a single server could fill this role. In practice, these services are in most cases distributed among several servers, each serving different applications.

The tasks described above, which occur at rather irregular intervals and involve a certain degree of complexity due to the lack of routine or process know-how, should be examined in order to determine whether they can be performed more efficiently by an external service provider. One question to be answered is whether it is necessary to keep the necessary knowledge in the company in order to be able to react faster than the external service provider. For example, for business critical systems. Security aspects should also be considered, as external persons gain access to the system. From now on, outtasking performance must be regularly monitored and checked for quality and documentation. A complete dependence on the external partner must not arise.
The SAP Security for Administrators training block covers the basics of security when using SAP systems. Participants receive training in basic security measures in the form of prevention and monitoring.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
The necessary skills and roles for the SAP basis are explained in detail in the recommendation Skills & Roles.
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.
