Authorizations in SAP BW, HANA and BW/4HANA
WHY ACCESS CONTROL
If the programme determines that both of the criteria set out in the previous bullet points are met, the criterion of equality shall apply. This means that the proposed values of the permission that is already in place and to be added will come from the same transaction. Thus, the programme does not add a new default permission to the permission tree.
The IF_IDENTITY interface of the CL_IDENTITY class provides various methods for maintaining the fields of the user master record. As a template for the implementation of the BAdIs, you can use the CL_EXM_IM_IDENTITY_SU01_CREATE implementation example, which automatically populates the SU01 transaction's surname, space number, phone, email address, user group, billing number, and cost centre fields. This example implementation does not provide an external data source; the user name is set as the last name and fixed values are used for the other fields. At this point, you must complete the implementation, depending on your requirements. There are several possible data sources for the user master data that you can access from the BAdI.
Customise evaluation paths in SAP CRM for indirect role mapping
Trace after missing permissions: Run the System Trace for Permissions (ST01 or STAUTHTRACE transaction) to record permission checks that you want to include in the role (see Tip 31, "Optimise Trace Evaluation"). Applications are logged through the Launch Permissions checks.
Another important factor that should be considered in an authorization concept is to use a uniform naming convention because, on the one hand, many things cannot be changed after the initial naming and, on the other hand, this ensures searchability in the SAP system. In addition, the preset authorization roles of the SAP system should never be overwritten or deleted, but only copies of them should be created, which can then be adapted as desired.
During go-live, the assignment of necessary authorizations is particularly time-critical. The "Shortcut for SAP systems" application provides functions for this purpose, so that the go-live does not get bogged down because of missing authorizations.
Dialogue users are intended for use by natural persons who log in to the SAP system via SAP GUI (dialogue login).
If the proliferation has arisen because there are errors and gaps in the authorization concept, these errors must be identified, eliminated and the authorizations optimized.
