Hi,
here's my view to this problem. Perhaps need some adjusting in join conditions when data model and data is clearer
create table t1 (
  id number,
  col1 varchar2(10)
insert into t1 values (314, 'somevalue2');
create table t2 (
  id number,
  id1 number,
  col2 varchar2(10)
insert into t2 values (314, 1, 'somevalue4');
insert into t2 values (314, 2, 'somevalue5');
insert into t2 values (314, 3, 'somevalue6');
create table t3(
    id  number,
    id1 number,
    id2 number,
    cod varchar2(3),
    qty number
insert into t3 values (314, 1, 1, 'LTR', 10);
insert into t3 values (314, 1, 2, 'KG', 20);
insert into t3 values (314, 2, 1, 'LTR', 40);
with ltr as (
  select id, id1, id2, cod, qty  from
    select id, id1, id2, cod as code, cod, qty from t3
  pivot
    sum(qty) for code in ('LTR' as qty)
  where qty is not null
), kg as (
  select id, id1, id2, cod, qty  from
    select id, id1, id2, cod as code, cod, qty from t3
  pivot
    sum(qty) for code in ('KG' as qty)
  where qty is not null
select
  t2.id,
  t2.id1,
  ltr.id2,
  ltr.cod,
  ltr.qty,
  kg.cod,
  kg.qty,
  t1.col1,
  t2.col2
from t2 join ltr on (
  t2.id = ltr.id and t2.id1 = ltr.id1
) full join kg on (
  t2.id = kg.id and t2.id1 = kg.id1
) left join t1 on (
  t1.id = t2.id
order by id, id1
drop table t1 purge;
drop table t2 purge;
drop table t3 purge;
table T1 created.
1 rows inserted.
table T2 created.
1 rows inserted.
1 rows inserted.
1 rows inserted.
table T3 created.
1 rows inserted.
1 rows inserted.
1 rows inserted.
        ID        ID1        ID2 COD        QTY COD        QTY COL1       COL2  
       314          1          1 LTR         10 KG          20 somevalue2 somevalue4
       314          2          1 LTR         40                somevalue2 somevalue5
table T1 dropped.
table T2 dropped.
table T3 dropped.
