Icon_history missing after upgrade

Hi Experts,

We have recently upgrdaed from SP6 to SP9 and after upgrade the standard icon is missing. Same thing is working fine in the quality system where upgrade activity is not yet performed.

Below is the code written to show the icon in table:

          l_v_icon = cl_bsp_mimes=>sap_icon( id = 'ICON_HISTORY' ).

          IF l_v_icon IS NOT INITIAL.
            CONCATENATE '<img src="' l_v_icon '" >' INTO l_v_icon.

         ENDIF.

          CREATE OBJECT l_ref_lnk.
          l_ref_lnk->id        = p_cell_id.
          l_ref_lnk->onclick   = 'DISPLAYFLOW'.
          l_ref_lnk->text      = l_v_icon.
          l_ref_lnk->reference = p_row_index.

          TRY.
              p_replacement_bee      = l_ref_lnk.
            CATCH cx_root.
          ENDTRY.

Kindly help.

Regards
