Hi everyone
I'm with a doubt about the roles functionalities and would like to
receive comments on the following scenario:
I have an on premise CRM 2011 Server, there is a parent Business Organization Unit and 2 child’s Business Units
[Business Organization UNIT]-> Here is located the admin user
- [Business Unit A] -> Here is the
sales person A
- [Business Unit B]-> Here is the sales person B
These are the securities roles applied to the A & B sales people:

The Sales person A creates an Account in the CRM
The System Admin creates an Opportunity for the Sales person’s Account, but the system admin is the opportunity owner and he doesn’t share it, later he creates activities and save them as complete.
When the Sales person A displays the open opportunities view he can see not only his opportunities but also the System admin opportunities.
When the Sales person A click on the account name, in the left he can read all the activities created and closed for that record.
* Here comes mi question:
How could this be possible if I setup in the roles map for the
Sales person A to read only his Opportunities and Activities?
