Data arrangement - need help

Question

Hi experts,
I have included the sql for the data as it is in the table and the format in which I am trying to display the data but would need your help. Many Thanks.
create table #DATA
(CustNum int,
weeknumber int,
tserial int,
code varchar(2),
amount money,
Bal money)
insert into #DATA values ( 100, 40 ,12, 'C', 13.60, 87.37)
insert into #DATA values ( 100, 41 ,15, 'D', 85.92, 73.77)
insert into #DATA values ( 100, 42 ,24, 'C' ,13.60, 159.69)
insert into #DATA values ( 100, 43 ,35, 'C',142.74, 146.09)
insert into #DATA values ( 100, 44 ,47, 'D', 85.92,3.35)
insert into #DATA values ( 100, 45, 55,'C',15.00,89.27)
select * from #DATA ORDER BY weeknumber desc
create table #Req_output
( CustNum int,
WeekNumber int,
Debit money,
Credit money,
Balance money
insert into #Req_output values(100, 45, Null, 15, 74.27)
insert into #Req_output values(100, 44, 85.92,Null, 89.27)
insert into #Req_output values(100, 43, Null,142.74,3.35)
insert into #Req_output values(100, 42, Null,13.60, 159.69)
insert into #Req_output values(100, 41, 85.92, Null,159.69)
insert into #Req_output values(100, 40, Null,13.60, 73.77)
select * from #Req_output
drop table #DATA
drop table #Req_output
Let me know if I have missed any details from the query above.
Thanks again !

Having such a balance column is not a good idea.
DECLARE @Improved TABLE
CustNum INT ,
weeknumber INT ,
tserial INT ,
code VARCHAR(2) ,
amount MONEY
INSERT INTO @Improved
VALUES ( 100, 1, 1, 'B', 87.37 ),
( 100, 40, 12, 'C', -13.60 ),
( 100, 41, 15, 'D', 85.92 ),
( 100, 42, 24, 'C', -13.60 ),
( 100, 43, 35, 'C', -142.74 ),
( 100, 44, 47, 'D', 85.92 ),
( 100, 45, 55, 'C', -15.00 );
SELECT * ,
SUM(amount) OVER ( ORDER BY tserial ASC ) AS ActualBalance
FROM @Improved
ORDER BY weeknumber DESC;
WITH Data
AS ( SELECT * ,
SUM(amount) OVER ( ORDER BY tserial ASC ) AS ActualBalance
FROM @Improved
SELECT D.CustNum ,
D.weeknumber ,
D.tserial ,
IIF(code = 'C', D.amount, NULL) AS Credit ,
IIF(code = 'D', D.amount, NULL) AS Debit ,
D.ActualBalance
FROM Data D
WHERE code != 'B'
ORDER BY D.weeknumber DESC ,
D.tserial DESC;
