ALV OO Event DOUBLE_CLICK

Question

Hi,
I´m using the Event DOUBLE_CLICK and HOTSPOT_CLICK. There are 3 Parameters and i dont know the different between the Parameter E_ROW and ES_ROW_NO (by HOTSPOT_CLICK named E_ROW_ID and ES_ROW_NO). Which Parameter is better as example to read an ITAB with INDEX? I have heared, the ES_ROW_NO is the better one. Really?
My other Problem is how to check, if the User clicked a Subtotal-Row. With the E_ROW i can check this by the ROWTYPE. If it´s filled, i think, it concerns about a Subtotal-Row. But, how it´s with the Parameter ES_ROW-NO?
Are there any experience?
Thanks you
