Reg : Adding new nodes to ALV tree using class CL_GUI_COLUMN_TREE

Hello All,

      I am Using the class to display ALV tree using CL_GUI_COLUMN_TREE class.

My functionality is to add new node or an item when user click on a button.

I have gone through standard SAP example programs before posting this,

but it uses different classes.

Is there any approach for adding a node or an item using this class.

With regards,

Sandeep Akella
