  DATA LO_EL_EMPLOYEE TYPE REF TO IF_WD_CONTEXT_ELEMENT.
  DATA LT_EMPLOYEE TYPE WD_THIS->ELEMENTS_EMP_DETAILS.
  DATA LS_EMPLOYEE TYPE WD_THIS->ELEMENT_EMP_DETAILS.
navigate from <CONTEXT> to <EMPLOYEE> via lead selection
  LO_ND_EMPLOYEE = WD_CONTEXT->GET_CHILD_NODE('EMP_DETAILS').
  DATA LO_EL_CONTEXT TYPE REF TO IF_WD_CONTEXT_ELEMENT.
  DATA LS_CONTEXT TYPE WD_THIS->ELEMENT_CONTEXT.
  DATA LV_EMP_NO LIKE LS_CONTEXT-EMP_NO.
  DATA LV_NUM TYPE I.
get element via lead selection
  LO_EL_CONTEXT = WD_CONTEXT->GET_ELEMENT(  ).
get single attribute
  LO_EL_CONTEXT->GET_ATTRIBUTE(
    EXPORTING
      NAME =  `EMP_NO`
    IMPORTING
      VALUE = LV_EMP_NO ).

      LT_EMPLOYEE  FROM PA9030 WHERE PERNR EQ LV_EMP_NO." AND ENDDA EQ '99991013'.
  DESCRIBE TABLE LT_EMPLOYEE LINES LV_NUM.
  LO_ND_EMPLOYEE->BIND_TABLE( LT_EMPLOYEE ).
  DATA LO_CMP_USAGE TYPE REF TO IF_WD_COMPONENT_USAGE.
  LO_CMP_USAGE =   WD_THIS->WD_CPUSE_ALV( ).
  IF LO_CMP_USAGE->HAS_ACTIVE_COMPONENT( ) IS INITIAL.
    LO_CMP_USAGE->CREATE_COMPONENT( ).
  ENDIF.

  L_REF_CONFIG_TABLE->SET_DISPLAY_AS( VALUE = L_DISPLAY_AS ).
ENDMETHOD.
