Dynamic Data Source Issue in RRC

Hi

I'm trying to do a table in rpe (getting data from a RRC PA) that populates a business requirement type artifact ("parent") and their business enhacements type artifact type  ("child") linked.
For example

In RRC I have :

Business Requirement Sample #1 --Embbeds--> Business Enhancement Sample #1

                                                      --Embbeds--> Business Enhancement Sample #2

So my table in RPE should be like this :

I have accomplished to  get the table to show the business requirement and their linked  business enhancement title but not the attributes.
