Distinct Type Count

I have a weird MDX request and I'm unsure of how to accomplish this.

My relation table has two fields Department(int) and Employee Type(int)

I need to get a distinct count of the number of distinct employee types per Department.

E.g for the data below: (calculated member) DistinctTypeCount=4 (when dep=1) (four distinct types of employees in this department

Dep. Emp. Type

-

1 23

1 2

1 4

1 23

1 4

1 4

1 10

Can anyone suggest an mdx query for this calculated member? If I redesigning the relational view on which the cube is based makes things easier I can definitely go that route.

How the fields are exposed in your UDM? Are they dimension attributes? What design has the dimension?

|||yes they are dimension attributes.
