Example 2
In this example, the roles and the group to which the user is assigned have privilege to the extension table.
Role 2 has the highest security of read/write access. Consequently, the user has privilege to view and edit the
         extension table in the object form. 
| User privilege | Role privilege | Group privilege | 
|---|---|---|
Role 1 = 
				  Read 
				                 Role 2 = 
					   | 
                  
                     Read 
				   
				               |
