Record Level Security for Financial Dimensions [AX 2009]

does anyone know how can i make record level security on the financial dimensions?

i have six dimensions and for certain security groups i need to allow them to view certain records in each dimension, for example i have a dimension called “department” and a dimension called “employee”, for a security group i need to allow them to see 2 or 3 departments only and few emaployees.

is this possible?
