Hello Rei,
you need to model the hierarchy using an association valuation. This is the example from the online help for the valuation keyword:
businessobject BusinessObject1 {
[AlternativeKey] element ID:ID;
node ChildNode[0,n] {
element ID:ID;
element ParentID:ID;
association Children [0,n] to ChildNode valuation (ParentID == ID);
}
}
The valuation keyword allows you to define an association with cardinality [0,n] on the ChildNode of BusinessObject1. The association Children is calculated by the system based on the condition on the ID and ParentID elements of ChildNode.
