Database layer (relational database management system)
SF01 Logical file paths and names (client-dependent)
In the beginning, in our company, the installation and management of the systems were dealt with by the functional consultants/consultants of the respective systems. The CRM consultant was responsible for the SAP CRM system, the SRM consultant for the SAP SRM, etc.
In addition to the consultants working in the individual SAP modules, there is a subarea here that is not directly apparent to many and whose activities seem to be quite opaque: SAP Basis. The smooth operation of SAP systems as the heart of many companies is ensured by the work of SAP Basis administrators.
Application layer
Introducing secinfo and reginfo files into an existing system landscape is associated with risk and effort. As already indicated in the two options, the workload increases greatly as the system landscape grows.
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.
