MDM Hierarchy Table Into Tree (Java WebDynpro)

Question

Hello all,
            I have a requirement of showing a MDM Hierarchy Table into Tree UI element.
These are the steps am following:
1) MDM Connectivity
2) Using RetrieveLimitedHierTreeCommand command to retrieve tree structure of the table
3) Using getChildren() method of each node to get the children
4) Made a tree ui element with a recursive node
Now since the Hierarchy table can reach any level of nodes how do i write code for dynamic tree node/leaf generation?
Please guide me through with detailed steps/code if possible?

Hi Yogesh,
After getting the HierNode you have to recursively populate the hierarchy tree using the below code:
  private void createHierarchyTree( parent_element, com.sap.mdm.data.HierNode HierNode)
     if(HierNode != null && HierNode .getChildren() != null)
          for(int iChildCount=0 ; iChildCount < HierNode .getChildren().length ; iChildCount++)
               IPublic<comp name>.Iparent_element objTreeElement = parent_element.node<Recursive node name>().create<name>Element();
               objTreeElement.setattr1(HierNode.getChildren()[iChildCount].getDisplayValue());
               objTreeElement.setattr1_Recid(HierNode.getChildren()[iChildCount].getId().id);
               parent_element.node<Recursive node name>().addElement(objTreeElement);
// call the method recursively               
createHierarchyTree(objTreeElement, HierNode.getChildren()[iChildCount]);
This will populate the tree, you need to create an action in the tree view and link it to TreeNode Type action property using which you can get the selected value.
Hope this helps!!
