How to remove parent as a child from a SSAS parent child dimension

In a parent child dimension, when an attribute's usage type is set as Parent and browsed from a client tool, many designers as well as users may get confused based on the displayed results.

Check your Digits

The most persistent struggle in data processing has been to ensure clean data. There are many ways that data can be incorrect and a database must check, as best it can, that the data is correct.
