In the queries below is an example of a many to many relationship that uses NUMBER as the linking field. When the attribute is used in combination with the [Measures] it is not doing the filter of the selected attribute. Is this a side affect of the many 2 many relationship that you can't use the attributes in combination with the Measures?
