Tranborg ,
I have asked same question couple months ago...
The answer is simple as the question: There's no similar for ADM2.
The ADM2 version has a "foreign field" treatment that solve this..
All you need is establish corrects data links between "father" SDO e "child" SDO, when you create a child record all foreign field are brought to the child record...
I hope i've answered you question...
