Hello,
Please check this code.
   DATA: k_node_layout TYPE lvc_s_lacn.
   CONSTANTS: c_checked VALUE 'X'.
   FIELD-SYMBOLS: <leaves>  TYPE table,
                  <leaf>    TYPE ANY.
Set the icon based on the parameter.
   k_node_layout-u_n_image  = c_checked.
   k_node_layout-u_exp_imag = c_checked.
Set the icon value based on the parameter.
   k_node_layout-n_image   = new_icon.
   k_node_layout-exp_image = new_icon.
Build the dynamic values for table and line.
   ASSIGN leaves->* TO <leaves>.
   CREATE DATA leaf LIKE LINE OF <leaves>.
   ASSIGN leaf->* TO <leaf>.
Get the associated line item for the selected node.
   tree->get_outtab_line( EXPORTING  i_node_key     = node_key
                          IMPORTING  e_outtab_line  = <leaf>
                          EXCEPTIONS node_not_found = 1
                                     OTHERS         = 2 ).
Update the icon of the node.
   tree->change_node( EXPORTING  i_node_key     = node_key
                                 i_outtab_line  = <leaf>
                                 is_node_layout = k_node_layout
                      EXCEPTIONS node_not_found = 1
                                 OTHERS         = 2 ).
Thanks.
Ramya.
