User and authorization management
Translating texts into permission roles
Applications use the ABAP statement AUTHORITY-CHECK in the source code of the program to check whether the user has the appropriate authorizations and whether these authorizations are defined appropriately, that is, whether the user administrator has assigned the values required by the programmer for the fields. In this way, you can also protect transactions that are indirectly accessed by other programs. AUTHORITY-CHECK searches the profiles specified in the user master record for authorizations for the authorization object specified in the AUTHORITY-CHECK statement. If one of the determined authorizations matches one of the specified values, the check was successful.

Access to tables and reports should be restricted. A general grant of permissions, such as for the SE16 or SA38 transaction, is not recommended. Instead, parameter or report transactions can help. These transactions allow you to grant permissions only to specific tables or reports. You can maintain secondary authorization objects, such as S_TABU_NAM, in the Sample Value Care.
Determine Permissions Error by Debugging
How do I make an authorization trace on a user (STAUTHTRACE)? With the authorization trace you can record which authorization objects are used by a user. This helps, for example, in the creation of suitable roles: - Call the transaction STAUTHTRACE - Specify the desired user and start the trace - Let the user call his transaction - Stop the trace (Important, do not forget!) - Evaluate the results.

You can influence the default behaviour of various transactions and parameters with the customising switches for the maintenance of Session Manager and Profile Generator as well as the user and permission management. The SSM_CID table gives you an overview of all customising switches supplied by SAP, specifying the relevant tables SSM_CUST, SSM_COL, PRGN_CUST and USR_CUST. The short description of the customising switch refers to the relevant and current SAP references. The actual settings can be found in the SSM_CUST, PRGN_CUST and USR_CUST tables.

For the assignment of existing roles, regular authorization workflows require a certain minimum of turnaround time, and not every approver is available at every go-live. With "Shortcut for SAP systems" you have options to assign urgently needed authorizations anyway and to additionally secure your go-live.

They include two switches for customising in the SSM_CUST table.

The settings are made in development and then transported to the other systems.
