It's very confused if I want to define a hierachy dim, I need to define it be normal or derived and then add it to aggregation group for hierachy dims. if this hierachy dims I want to define includes 3 columns, it will be 3 dims if define it in normal dims or 1 dim if define it in derived dims. So how to handle it ?
