What is a parent hierarchy?

What is hierarchy in SAP Analytics Cloud?

Hierarchies are a great way to save space in your Story since a lot of information can be packed into a single chart.
Why are parent-child hierarchies have variable depth?
Because of their nature, parent-child hierarchies may also have a variable depth: the number of levels traversing the hierarchy top to bottom can be different depending on the navigated path. For these reasons, a parent-child hierarchy should be implemented following the technique described in this pattern.
How is a parent-child hierarchy different from a level based hierarchy?
A parent-child hierarchy is a hierarchy of members that all have the same type. This contrasts with level-based hierarchies, where members of the same type occur only at a single level of the hierarchy.

How are parent child hierarchies implemented in tabular?
The parent-child pattern implements some sort of self-join of the table containing the entities, which is not supported in Tabular. Because of their nature, parent-child hierarchies may also have a variable depth: the number of levels traversing the hierarchy top to bottom can be different depending on the navigated path.
