HIER_DEPTH returns a number representing the level depth of either all members of a hierarchy or a particular member, where 0 is the top level. The hierarchy can be either level-based or value-based.
NUMBER
HIER_DEPTH ( [member_expression] [WITHIN] {DIMENSION dimension_id | HIERARCHY hierarchy_id} )
Identifies a single dimension member within the hierarchy used for the calculation. If this optional argument is specified, then the result does not vary across dimension members.
The dimension over which the values are calculated using the default hierarchy.
The hierarchy over which the values are calculated. If dimension_id is used instead, the default hierarchy is used.
This example returns the depth of each member in the default hierarchy of the Time dimension.
