In this scenario, the base dimension (Product) is not present in the worksheet and the level 0 attribute member (Caffeinated_True) is in a column. A drill down on Caffeinated_True pivots it to the innermost row. The members of the base dimension associated with the level 0 attribute member display to the right of the row.
Before drill down: Caffeinated_True is in a column.
After drill down: Caffeinated_True pivots to a row inside of Year. 100-10, 100-20, 200-10, 200-20, 300-10, 300-20, and 300-30 are members of Product with the attribute Caffeinated_True. These members are displayed in a row to the right of Caffeinated_True.
