cl_gui_alv_grid: hide subtotal line but use get_subtotal method

Hi,

I tried to use LOOP AT... . at the first place to calculate subtotal, but found get_subtotal method provides more flexibility. I based many checking on that

                     AT NEW ... .

                     ENDAT.

                   ENDLOOP.

method but now, I was required to hide the subtotal line. Is it possible to hide the subtotal line but still enable the subtotal calculation at the background?

Best regards,

ts
