Trying to create a filtered measure in a Universe based on a BEx query

I'm using a Universe based on a BEx query against a BW cube and trying to create a measure filtered by a value type. I used the Where function but no data is returned when I use the field. Here are the properties:

Select:

@Select(Key Figures\***Net Sales)

Where:

<FILTER EXPRESSION="@Select(Value type\L01 Value type Key)"><CONDITION OPERATORCONDITION="Equal"><CONSTANT CAPTION="10"></CONSTANT></CONDITION></FILTER>

Any tips on the best way to do this would be appreciated.
