3267060 - Authorization restriction for displaying detection results

Detect results are saved in Alerts. How to restrict display range according to..

for example, company code.

User A belongs to company 1000.
User B belongs to company 2000.

User A is allowed to check the detection results of company 1000 only.
Does the Access group in Authorization Object FRA_ALERT allow such a control?  

Also, need 2 Roles (Fiori front end and S/4 backend).

- SAP_BR_ACS_INVESTIGATOR  
- SAP_FRA_FRAUD_INVESTIGATOR

Both Roles have Authorization object FRA_ALERT,
Field FRA_AG (access group).

Do we have to input the same access group for both Roles?
