Modeling hierarchies with nodes having multiple assignments

Question

Hello,
In IS-Health, there are cases where an organizational hierarchy has a node assigned to multiple higher nodes. Whilst R/3 - IS-H seems to accept this, BW hierarchies seems to fail during data loads. Apparently, this requires an innovative modeling approach. We did try generating a unique number range during extraction, but were forced to abandon this approach due to field length restrictions. Would be nice to hear from others on this subject.
Regards

Use this example...
public class TreeDemo {
private JFrame frame;
private JTree tree;
public TreeDemo (JTree tr) throws Exception {
frame=new JFrame();
frame.getContentPane().setLayout(new BorderLayout());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
edit=new JEditorPane();
frame.getContentPane().add frame.getContentPane().add(tr,BorderLayout.CENTER);
frame.getContentPane().add(new JButton("ok"),BorderLayout.SOUTH);
frame.pack();
frame.show();
public static void main(String[] argv)
throws Exception
Vector v=new Vector();
v.add(0,"c:\\first\\abc");
v.add(1,"c:\\first\\abc\\word1.doc");
v.add(2,"c:\\first\\abc\\description.doc");
v.add(3,"c:\\first\\def ");
v.add(4,"c:\\first\\der\\tor1.doc");
TreeDemo html = new TreeDemo (createTree(v));
private static JTree createTree(Vector v) {
JTree tree = null;
DefaultMutableTreeNode root = null;
Iterator i = v.iterator();
String subStr;
DefaultMutableTreeNode parent=null;
root = new DefaultMutableTreeNode("ROOT");
tree = new JTree(root);
parent=root;
while (i.hasNext()) {
String path = (String)i.next();
StringTokenizer st = new StringTokenizer(path,"\\");
while (st.hasMoreTokens()) {
subStr = st.nextToken();
DefaultMutableTreeNode current=findObject(parent,subStr);
if (current==null) {
DefaultMutableTreeNode node = new DefaultMutableTreeNode(subStr);
parent.add(node);
parent=node;
else {
parent=current;
parent=root;
return tree;
private static DefaultMutableTreeNode findObject(DefaultMutableTreeNode parent,String value) {
for (int i=0; i<parent.getChildCount(); i++) {
DefaultMutableTreeNode node=(DefaultMutableTreeNode)parent.getChildAt(i);
if (node.getUserObject().equals(value)) {
return node;
return null;
best regards
