Cube | Data Access | Data Cell Access Security/Slice Security by U1#Geography

Data Management Access Security
Please share your expertise to set up a Cube's Data Cell Access Security / Slice Security to limit data read access as outlined below:

Dimension: U1# - Geography
Total_Geography = Child 1 + Child 2 = Total / Top
         North_America = Child 1 / NA
         International = Child 2 / Int'l

Slice Security: Access Level - Read Data by Geography - in a CV and a QV
Total_Geo_Data = Read Total data | Read NA data and Read Intl data
         NA_Data = Read NA data | no data access = International and Total
         Intl_Data = Read Int'l data | no data access = North America and Total
