Cube access control
READ access allows a user to view cubes and/or data within cubes but does not allow a
user to change data within that cube.
WRITE access allows a user to view cubes and/or data within cubes and to change that data. For a user or a role to be assigned WRITE access to a cube, they must also have global permission.
NONE access to a specific cube means the user will not see that cube in any list of available cubes. If they try to access the cube from a worksheet, no values are returned. If there is an OLAP rule where the user has access to target cell and source has a reference to the restricted cube, users see that formula's result.
