SELECT ID2, SUM(Amount1), SUM(Amount2)
FROM   (SELECT ID2, Amount AS Amount1, 0 AS Amount2
        FROM   Table1
        UNION ALL 
        SELECT ID2, 0, Amount
        FROM   Table2) AS u
GROUP BY ID2

drop table if exists dbo.test_T1;
go
create table dbo.test_T1(
  ID1       varchar(8) not null,
  ID2       varchar(8) not null,
  Amount1   int not null);
go
alter table dbo.test_t1
add constraint
  pk_T1 primary key clustered (ID1, ID2);  
go

insert dbo.test_T1(ID1, ID2, Amount1) values
('A1', 'B1', 10),
('A1', 'B2', 20),
('A2', 'B1', 15);

drop table if exists dbo.test_T2;
go
create table dbo.test_T2(
  ID3       varchar(8) constraint pk_T2 primary key not null,
  ID2       varchar(8) not null,
  Amount2   int not null,
  ID1       varchar(8) not null);
go

insert dbo.test_T2(ID3, ID2, Amount2, ID1) values
('C1', 'B1', 5, 'A1'),
('C2', 'B1', 2, 'A1');

--select * from dbo.test_T1;
--select * from dbo.test_T2;

with t2_cte(ID1, ID2, Amount2) as (
    select ID1, ID2, sum(amount2) from dbo.test_T2 group by ID1, ID2)
select
 t1.ID2,
 sum(t1.Amount1) Amount1,
 sum(isnull(t2.Amount2, 0)) Amount2
from
  dbo.test_T1 t1
 left join
  T2_cte t2 on t1.ID1=t2.ID1
               and t1.ID2=t2.ID2
group by
  t1.ID2;

SELECT t1.ID2, SUM(t1.Amount1) AS Amount1, ISNULL(MAX(t2.Amount2), 0) AS Amount2
FROM dbo.table1 t1
LEFT OUTER JOIN (
    SELECT ID2, SUM(Amount2) AS Amount2
    FROM dbo.table2
    GROUP BY ID2
) AS t2 ON t2.ID2 = t1.ID2
GROUP BY t1.ID2
