MS Dynamics 365 v9 On prem.
We need to regulate permission to view opportunities within the account.
For example User A should be able to see all the opportunities of the Account, and User B should be able to see only own.
The permissions should work within the Account, not the Business unit or smth like this, so security roles don't fit our needs (users have Read on organization level for the Accounts and User level for Opportunitites).
Now we have Access Team set up for the account - but in this case all the users added to access team can see all the opportunities for the account, there is no way to restrict to only own.
