Save data to a table (In the View method)

Question

Hi,
   I am new to Webdynpro.We have a requirement in BW to update user config tables using webdynpro.I got the retrieve data part working.
  Now I am trying to save data back to the table.I got the following code in the save method which will be called when the save button is clicked.
method ONACTIONSAVEDATA .
data:
      TABLE_NODE type ref to IF_WD_CONTEXT_NODE,
      varTable    type standard table of ZUSRCONFIG.
      TABLE_NODE = WD_CONTEXT->GET_CHILD_NODE( 'TABLE_N1' ).
endmethod.
How can I get the data from the TABLE_NODE so that I can use a update command subsequently.TABLE_NODE in the context is bound to ZUSRCONFIG table.
Thanks

hi siva...
here is the code :
DATA lo_nd_node_table TYPE REF TO if_wd_context_node.
  DATA lo_el_node_table TYPE REF TO if_wd_context_element.
  DATA ls_node_table TYPE wd_this->element_node_table.
navigate from <CONTEXT> to <NODE_TABLE> via lead selection
  lo_nd_node_table = wd_context->get_child_node( name = wd_this->wdctx_node_table ).
@TODO handle not set lead selection
  IF lo_nd_node_table IS INITIAL.
  ENDIF.
get element via lead selection
  lo_el_node_table = lo_nd_node_table->get_element(  ).
@TODO handle not set lead selection
  IF lo_el_node_table IS INITIAL.
  ENDIF.
alternative access  via index
lo_el_node_table = lo_nd_node_table->get_element( index = 1 ).
@TODO handle non existant child
IF lo_el_node_table IS INITIAL.
ENDIF.
get all declared attributes
  lo_el_node_table->get_static_attributes(
    IMPORTING
      static_attributes = ls_node_table ).
ls_node_table will containe the values of your table.
