Hi Francesco,
This sounds like a case of preventing self-approval. See the link below for more info.
If you place a request for yourself or someone else where you’re the approval, SailPoint will reassign it to your manager by default. If you don’t have a manager, it will reassign it to a SailPoint admin. I’m assuming in your case, you may not have a manager or they have redirected approals elsewere
You can change the default behaviour as mentioned in the article using the following API: set-access-request-config | SailPoint Developer Community . Alternatively, an access request administrator can reassign requests in the Dashboard → Access Request Administration interface.
Hope this helps!
