Features of the SAP authorization concept
Ensuring secure administration
When you select the row with the parameter transaction you created and click on the Suggest values button, the S_TABU_NAM authorization object is automatically created with the correct suggestion values, i.e. the table name in the transaction SU24. Check these suggestion values by clicking Yes in the S_TABU_NAM column. You will now end up in a view from the transaction SU24 and can check in the tables authorization objects and Permission Proposition Values (for all authorization objects) which changes to the object S_TABU_NAM have been made automatically. For more information and implementation guidance, use SAP Note 1500054. The SAP Note also provides the SUSR_TABLES_WITH_AUTH analysis report, which specifies table permissions for users or individual roles. This report checks at user or single-role level which tables have permissions based on the S_TABU_DIS or S_TABU_NAM authorization objects. The report does not check whether the user has the transaction startup permissions that are also necessary, such as S_TCODE. For example, if you check what table permissions a particular user has based on the S_TABU_DIS authorization object, you will receive information about the table names, the associated table permission group, and the eligible activities. Granting permissions to access tables directly is flexible and useful, and is not recommended unless the mechanism is hammered out by giving the user general table access through generic maintenance tools.
If you have defined the roles to the extent that the essential processes are depicted, then you will technically check which organisational features they contain (organisational levels, but also cost centres, organisational units, etc.). You then compare the technical result with the result from the consideration of the structure organisation and the business role description. A likely result is that you do not have to use all technical organisational features for differentiation. A possible result is that you want to add fields such as the cost centre to the organisation level.

The SAP authorization concept protects transactions and programs in SAP systems on the basis of authorization objects. Authorization objects enable complex checks of an authorization that are bound to several conditions. Authorizations represent characteristics of authorization objects depending on the employee's activity and responsibility. The authorizations are combined in an authorization profile that belongs to a role. The administrator assigns the appropriate role to the employee via the user master record so that the employee can perform his or her tasks in the system.
SAP customers do not maintain suggested values in this transaction. However, there are cases where data in the SU22 transaction is maintained in a customer environment. If TADIR services or external services are developed by the customer or partner, these services are not available by default in the SU22 transaction or the SU24 transaction. For these services, the header data must first be written to the USOBHASH table, which serves as the basis for maintaining the services. These entries in the USOBHASH table are generated automatically when running TADIR services. Read Tip 41, "Add external services from SAP CRM to the proposal values", for dealing with external services. Once the data in this table is available, you have the option to maintain the proposed values.
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.
The survey programme (transaction USMM), the results of which you transmit to SAP, serves this purpose.
