REUSE_ALV_LIST_DISPLAY 'END OF LIST' EVENT

Hai guys,

I display a list with REUSE_ALV_LIST_DISPLAY .

i sorted the list with companycode ebfore display.

i gave bukrs descrption as header using 'TOP_OF_PAGE'.

now the final display has a list for each company code,as desired.

also the ehar is fine.

but now i want 'total' at the end of lsit for each company code.

i TRIED .'END_OF_PAGE'. 'END_OF_LIST'. for this,but failed..
