Using Hierarchies in CDS views

Hello experts.

I understand CDS views allow the use of hierarchies.

I did find the following annotation but I don't know how it works and if it suits my need.

@ObjectModel.dataCategory: #HIERARCHY

Can anybody tell me how to use it to access a Profit Center hierarchy I can access via the KCH3 TCode ?

Or, if it's not possible using this statement, what approach must I adopt then?

Thanks for your kind help.

Sebastien.
