Hi,
Please check this...
  DATA lo_nd_pack_mat TYPE REF TO if_wd_context_node.
  DATA lo_el_pack_mat TYPE REF TO if_wd_context_element.
  DATA ls_pack_mat TYPE wd_this->Element_pack_mat.
  DATA lt_pack_mat TYPE wd_this->Elements_pack_mat.
  DATA lv_pack_material TYPE wd_this->Element_pack_mat-pack_material.
  DATA: wa_temp TYPE REF TO if_wd_context_element,
        lt_temp TYPE wdr_context_element_set.
navigate from <CONTEXT> to <PACK_MAT> via lead selection
  lo_nd_pack_mat = wd_context->get_child_node( name = wd_this->wdctx_pack_mat ).
  CALL METHOD lo_nd_pack_mat->get_selected_elements
    RECEIVING
      set = lt_temp.
LOOP AT lt_temp INTO wa_temp.
    CALL METHOD wa_temp->get_static_attributes
      IMPORTING
        static_attributes = ls_pack_mat.
    lv_pack_material = ls_pack_mat-pack_material.
    if lv_pack_material is initial.
      lo_api_controller ?= wd_This->Wd_Get_Api( ).
      CALL METHOD lo_api_controller->GET_MESSAGE_MANAGER
        RECEIVING
          MESSAGE_MANAGER = lo_message_manager.
report message
      CALL METHOD lo_message_manager->REPORT_ATTRIBUTE_ERROR_MESSAGE
        EXPORTING
          MESSAGE_TEXT         = 'Please Select Packing Material...'
          ELEMENT              = wa_temp
          ATTRIBUTE_NAME       = 'PACK_MATERIAL' .
   exit.
    endif.
    append ls_pack_mat to lt_pack_mat.
    CLEAR ls_pack_mat.
  ENDLOOP.
  lo_nd_pack_mat->bind_table( new_items = LT_PACK_MAT
                                 SET_INITIAL_ELEMENTS = abap_false ).
