SAP FICO Authorizations
The goal of an authorization concept is to provide each user with the appropriate authorizations in the system individually for their tasks according to a previously defined rule. For this purpose, an authorization concept must be defined as the foundation for efficient authorization assignment. In this way, each employee is given system access through the role-specific assignment of authorizations according to his or her tasks. On the one hand, this protects sensitive information and, on the other, prevents damage caused by incorrect use of data.
The most important security services regarding permissions are the EarlyWatch Alert (EWA) and the SAP Security Optimisation Service (SOS). You compare the settings in your SAP systems with the recommendations of SAP. Both services are delivered as partially automated remote services; You can also use the SOS as a fully automated self-service. The EWA and SOS shall carry out eligibility tests, the results of which shall always be as follows: The heading indicates the check in question. A short text describes the importance of the audited entitlement and the risk of unnecessary award. A list indicates the number of users with the validated permission in the different clients of the analysed SAP system. The SOS also allows you to list the users. In the SOS, a recommendation is made for each check to minimise the identified risk. A final formal description represents the checked permissions. However, not only the explicitly mentioned transactions are evaluated, but also equivalent parameter or variant transactions.

Ensure that permission checks are performed when reference users are assigned. The checks are performed on the permissions associated with the roles and profiles assigned to the reference user. These eligibility tests are also a novelty, which is supplemented by SAP Note 513694.
Make sure that reference users are assigned minimal permissions to avoid overreaching dialogue user permissions. There should be no reference users with permissions that are similar to the SAP_ALL profile.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
If you want to copy clients, you have to set this parameter to 0 again before you do so, because the user SAP* is required for this.
You will notice, however, that the displayed services represent only a small part of the external services in the role menu.
