You can try using ROLLUP and GROUPING SETS like how some of the other forum members have suggested. Another way of getting the desired output would be :
with t as
select 'Aa' col1, 1 col2, 'Con' col3, 100 col4, 10 col5, -1 col6 from dual
union all
select 'Ba', 2, 'Cam', 50, 2, 33 from dual
union all
select 'Aa', 1, 'Con', 200, 20, -2 from dual
union all
select 'Ca', 3, 'val', 2, 5, -10 from dual
union all
select 'Aa', 1, 'Con', 150, 30, -3 from dual
union all
select 'Ba', 2, 'Cam', 20, 3, 11 from dual
union all
select 'Ca', 3 ,'val', 3, 5, -20 from dual
union all
select 'Ba', 2, 'Cam', 30, 5, 22 from dual
union all
select 'Ca', 3, 'val', 5, 4, -30 from dual
select * from
    select * from t
    union all
    select distinct * from
        select col1 || '-' || col3 || ' Sub-total' col1, null col2, null col3,
        sum(col4) over (partition by col1 order by col1) col4,
        sum(col5) over (partition by col1 order by col1) col5,
        sum(col6) over (partition by col1 order by col1) col6
        from t
order by col1, col2, col3
Output:
"COL1"     "COL2"     "COL3"     "COL4"     "COL5"     "COL6"
"Aa"     "1"     "Con"     "150"     "30"     "-3"
"Aa"     "1"     "Con"     "100"     "10"     "-1"
"Aa"     "1"     "Con"     "200"     "20"     "-2"
"Aa-Con Sub-total"     ""     ""     "450"     "60"     "-6"
"Ba"     "2"     "Cam"     "50"     "2"     "33"
"Ba"     "2"     "Cam"     "20"     "3"     "11"
"Ba"     "2"     "Cam"     "30"     "5"     "22"
"Ba-Cam Sub-total"     ""     ""     "100"     "10"     "66"
"Ca"     "3"     "val"     "5"     "4"     "-30"
"Ca"     "3"     "val"     "2"     "5"     "-10"
"Ca"     "3"     "val"     "3"     "5"     "-20"
"Ca-val Sub-total"     ""     ""     "10"     "14"     "-60"
