create an instance with BOPF FBI

Hi everyone,

I am trying to create an instance of BO (AAA), which has a representation sub-node. The representation sub-node refers to another BO (BBB).

actually the sub-node is only a reference of BO (BBB) and the node instance already exist.

should I create a sub-node for BO(AAA)? or I can through the association assign a reference of BO(BBB) to sub-node of Bo(AAA)?

thanks in advance.
