Add external services from SAP CRM to the proposal values
Controlling permissions for the SAP NetWeaver Business Client
If these issues are not taken into account during a conversion, there will be an imbalance between the system and the components to be protected, since the change in the system constellation means that new components, such as those mentioned above, must also be taken into account. Otherwise, a company may suffer economic damage and the resulting damage to its image. Furthermore, neglect of legal requirements (BDSG, DSGVO, GOB, HGB, etc.)1 can lead to legal measures or steps.
You can view the change documents of the permission proposal maintenance using the report SU2X_SHOW_HISTORY (available with the support package named in the SAPHinweis 1448611). If the note is not implemented, use the USOBT_CD and USOBX_CD tables. We recommend that you run the SU24_AUTO_REPAIR correction report regularly. This report cleans up inconsistencies and adds missing modification flags in the transaction SU24 data that may turn up as errors when the transaction SU25 is executed. Read SAP Note 1539556 for this. Modification flags are added to the records in transaction SU24, if they have been modified by you. You can see these flags in the USOBT_C and USOBX_C tables.
Define S_RFC permissions using usage data
You can use authorization objects to restrict access to tables or their content through transactions, such as SE16 or SM30. The S_TABU_DIS authorization object allows you to grant access to tables associated with specific table permission groups. You can view, maintain, and assign table permission groups in transaction SE54 (see Tip 55, "Maintain table permission groups"). For example, if an administrator should have access to user management tables, check the permission status using the SE54 transaction. You will notice that all the user management tables are assigned to the SC table permission group.
DDIC: DDIC is the only user able to log in or make changes to the ABAP Dictionary during installations and release changes. It is also used in the client 000, e.g. for certain jobs or Unicode conversions. DDIC exists in all clients except 066. Safeguard measures: In all systems (except for client 000 due to upgrade features), set DDIC to the System user type. If necessary, you can switch it back to a dialogue user using the Emergency User. Change the password, assign the user to the SUPER user group, and log it with the Security Audit Log.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
To do this, create an amendment in the system recommendations for the SAP hints to be implemented.
The website www.sap-corner.de offers a lot of useful information about SAP authorizations.
For medium-sized companies, the use of an authorization tool is usually also worthwhile.
