  • Parent-Child Hierarchies

    DAX does not directly support parent-child hierarchies. To obtain a browsable hierarchy in the data model, you have to naturalize a parent-child hierarchy. DAX provides specific functions to naturalize a parent-child hierarchy using calculated columns. The complete pattern also includes measures that improve the visualization of ragged hierarchies in Power Pivot. » Read more
