Application Permissions
Detect critical base permissions that should not be in application roles
SAPCPIC: SAPCPIC is not a dialogue user, but is used for EDI usage in older releases (EDI = Electronic Data Interchange); in default, SAPCPIC has permissions for RFC access. However, you should not use this user for them, nor for batch processes, but you must create other users for these applications. Safeguard measures: Lock down the user, change the password, assign it to the SUPER user group and log it with the Security Audit Log.
No more users can be created, maintained or deleted without the assignment of a valid user group. If a user group is not assigned when a user is created, the user is automatically assigned the default user group. Before you set the USER_GRP_REQUIRED switch, a user group must have been assigned to each existing user and the administrators must have the permissions for the default user group. When creating a new user, the default user group will be used as pre-occupancy; this user group can be overridden by setting another user group in the S_USER_GRP_DEFAULT user parameter for each user administrator. The customising switch requires a valid user group, because it is used as the default user group. If a valid user group has not been entered in the customising switch, the user group is nevertheless a mandatory field. This will lead to errors in automated user creation.
Standard authorisation
Before you start and define critical permissions, you should identify your core business processes or functions and then map the conflicting processes in meaningful combinations as so-called risk. The RSUSR008_009_NEW report cannot replace a GRC system (GRC = Governance, Risk, and Compliance) with the SAP Access Control component. Rather, this report should be understood and used as an indicator of the current system state. The report identifies the users that have the critical permission combinations defined in the USKRIA table. The identifier, which can also be called a risk ID, describes a combination of authorization objects with field names and field values. These are linked to one of the two operatives AND or OR available.
In order to avoid inconsistencies during the release of the transport order, all the roles on the order will be blocked during release. If roles cannot be locked, the job release fails. You can see the reason for the failed share and the cause of other errors in the transport log.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
