How to use the 0REOBJECT_HIER data source?

Hi,

I'm trying to found a relationship between the Rental Objects and Rental Spaces and I found that I can do this using this DataSource(0REOBJECT_HIER).

I have activated this data source, but when I try to create the transformation between this datasource and 0REOBJECT (hierarchies) the fields don't match.

I didn't find this transformation in the business content, and there is no information about how to use this DataSource.

Do you have any idea?, Im new using hierarchies.

i will appreciate your help.

Thank you
