How Highlight a CELL on an ALV table

Question

Hi all!
I'm trying to do some checks on an input field of an ALV table component. But using REPORT_ATTRIBUTE_T100_MESSAGE it doesn't highlight the CELL of the row if the check hasn't been passed succesfully.
I've used this source code but nothing appears on the screen, no message and no cell highlighted. I put my source code for more information:
LOOP AT lt_data_mod INTO ls_data_mod.
alternative access via index
lo_el_n_empleado = lo_nd_n_empleado->get_element( index = ls_data_mod-index ).
CHECK VALUE
report message
CALL METHOD wd_comp_controller->go_message->report_attribute_t100_message
EXPORTING
msg = ls_msg
element = lo_el_n_empleado
attribute_name = ls_data_mod-attribute. " The name of input field that it is being modified
All that source code is in ON_DATA_CHECK event of ALV component.
Can anyone help me ?
Thanks!

Hello,
I put my source code:
ON_DATA_CHECK event of ALV:
  lt_data_mod[] = lr_data->t_modified_cells[].
  LOOP AT lt_data_mod INTO ls_data_mod.
alternative access  via index
lo_el_n_empleado = lo_nd_n_empleado->get_element( index = ls_data_mod-index ).
get all declared attributes
    lo_el_n_empleado->get_static_attributes(
      IMPORTING
        static_attributes = ls_n_empleado ).
Leemos la información inicial para hacer posteriormente los recalculos.
    READ TABLE wd_this->gt_empleados_inicial INTO ls_empleados_inicial WITH KEY pernr = ls_n_empleado-pernr.
    ASSIGN ls_data_mod-r_value->* TO .
Fijamos el valor del campo INCIN o PERIN en función de si el usuario ha modificado el valor en pantalla
    IF ls_data_mod-r_value NE ls_data_mod-r_old_value AND
        GE ls_n_empleado-incsu.
      IF ls_data_mod-attribute = 'INCPA'.
        ls_n_empleado-incin = abap_true.
      ELSEIF ls_data_mod-attribute = 'PERVC'.
        ls_n_empleado-perin = abap_true.
      ENDIF.
ELSEIF <fs_data> LT ls_n_empleado-incsu. " Check if user entry is less than incsu value then throw message...
      wd_comp_controller->show_message_2( imp_element = lo_el_n_empleado
                                                                           imp_msgno   = '622'
                                                                           imp_attr    = ls_data_mod-attribute ). " El valor introducido es menor que el "                 incremento sugerido
    ENDIF.
METHOD show_message_2 .
  DATA lv_message_id TYPE string.
  DATA ls_msg TYPE symsg.
  ls_msg-msgty = 'E'.
  ls_msg-msgid = 'ZHR_CM'.
  ls_msg-msgno = imp_msgno.
report message
  CALL METHOD wd_this->go_message->report_attribute_t100_message
    EXPORTING
      msg            = ls_msg
      element        = imp_element
      attribute_name = imp_attr.
ENDMETHOD.
Also I've tried with report_element_t100_message method but nothing happens.
Thank you.
