Row id in editable ALV while using MP_MOD_ROWS

Hi Experts

I have an editable alv with 13 fields editable in it. Inside the DATA_CHANGED event i am making use of the attribute MP_MOD_ROWS for doing some specific validations. But I am not able to pass the row_id to the the mehod add_protocal_entry while multiple rows are in MP_MOD_ROWS ,since its not available MP_MOD_ROWS .

Can anyone tell me how i can get the row_id for each row in MP_MOD_ROWS.

Since I need the full row for validations , i cant use MT_MOD_CELLS.
