Loading multiple level datamodel

Good morning, I am writing to ask about how to do (in PlanetPress Connect) a datamapper based on a connection to MS Access that is able to load the records that returns the query in 3 levels of nesting in the DataModel.

I explain, the Access table to which I connect contains 3 kinds of data: commercial (first level)  clients (second level)  invoices (third level)
I have established the “Boundaries” in OnChange of “idComercial” (primary key of first level).

What I intend is to load the commercials in “record” of the DataModel, the clients in “record. Client” and the invoices in “record. Client. Invoice”.
The problem I find is that it is not easy to build more than two levels (“Record” and “record. Client”).

Can you help me?

Thanks in advance,

Can you paste an snapshot of you datamodel so I can comprehend better your dilemma?

Here it is:
