Answer 1

probaby not the best performance, but you have a PRODUCT IN () list, which is what you wanted
with t as (
select 1 inv_no, 1 product, 2 sold_qty from dual union all
select 1, 2, 3 from dual union all
select 1, 3, 1 from dual union all
select 2, 2, 11 from dual union all
select 2, 3, 12 from dual union all
select 3, 2, 10 from dual union all
select 4, 3, 22  from dual
, tt as (
select t1.*, (select count(*)
              from   t t2
              where  product in (2,3)
              and    t1.inv_no = t2.inv_no) cn
from t t1
select * from tt
where cn > 1
