I need to fix payout issue - example given below (re-edited) - sql

Question

Customer Table (usage is kwH)
+----+----------+------------+----------+----------+----------+-------+-------+
| ID | Customer | Account_no | Meter_no | Supplier | Active | Usage | Repid |
+----+----------+------------+----------+----------+----------+-------+-------+
| 1 | Joe | 123 | 111 | NSTAR | active | 20 | 100 |
| 2 | Joe | 123 | 222 | NSTAR | active | 30 | 100 |
| 3 | Joe | 123 | 150 | NSTAR | inactive | 60 | 100 |
| 4 | Sam | 456 | 352 | SEP | active | 50 | 100 |
| 5 | Jill | 789 | 222 | FES | active | 40 | 200 |
| 6 | Mike | 883 | 150 | ABB | inactive | 40 | 200 |
+----+----------+------------+----------+----------+----------+-------+-------+
Payment_Receive (table)
+------------+----------+-------------+-------------+
| Account_no | Supplier | Amount_paid | PaymentDate |
+------------+----------+-------------+-------------+
| 123 | NSTAR | 20 | 2011-11-01 |
| 456 | SEP | 40 | 2011-11-01 |
| 456 | SEP | -40 | 2011-11-01 |
| 456 | SEP | 40 | 2011-11-01 |
| 789 | FES | 50 | 2011-11-01 |
| 883 | ABB | 30 | 2011-11-01 |
+------------+----------+-------------+-------------+
The two tables are use for rep payout. We do not have control over the payout_table because it comes from outside. This creates certain problems because we can not do one-to-one match between the two tables. Leaving that aside, I would like to have payout calculated for RepID = 100 with certain criteria. This is the output I would like to see for RepId = 100
+------------+----------+-------------+-------------+-------------+
| Account_no | Supplier | Amount_paid | Usage | PaymentDate |
+------------+----------+-------------+-------------+-------------+
| 123 | NSTAR | 20 | 60* | 2011-11-01 |
| 456 | SEP | 40 | 50 | 2011-11-01 |
| 456 | SEP | -40 | 40 | 2011-11-01 |
| 456 | SEP | 40 | 40 | 2011-11-01 |
+------------+----------+-------------+-------------+-------------+
Note here that
Account_no 123 exists twice in customers table, it must show one time in rep payout
3 amounts were paid to account_no 456, all the three must show in the report
Reports are calculated on Monthly basis
Script for example (Updated with Usage column)
create database testcase
go
use testcase
go
create table customers (
id int not null primary key identity,
customer_name varchar(25),
account_no int,
meter_no int,
supplier varchar(20),
active varchar(20),
usage int,
repid int
)
create table payments_received (
account_no int,
supplier varchar(20),
amount_paid float,
paymentdate smalldatetime
)
insert into customers values('Joe',123, 111,'NSTAR','active',20,100)
insert into customers values('Joe',123, 222,'NSTAR','active',30, 100)
insert into customers values('Joe',123, 150,'NSTAR','inactive',60,100)
insert into customers values('Sam',456, 352,'SEP','active',40,100)
insert into customers values('Jill',789, 222,'FES','active',40,200)
insert into customers values('Mike',883, 150,'ABB','inactive',40,200)
select * from customers
insert into payments_received values(123,'NSTAR',20,'2011-11-01')
insert into payments_received values(456,'SEP',40,'2011-11-01')
insert into payments_received values(456,'SEP',-40,'2011-11-01')
insert into payments_received values(456,'SEP',40,'2011-11-01')
insert into payments_received values(789,'FES',50,'2011-11-01')
insert into payments_received values(883,'ABB',30,'2011-11-01')
select * from payments_received
Updated: Updated The question and script
Usage been added to Customers table
Usage must appear int the result table
*60 = Notice that there are 2 active records (and one inactive). This could be the sum of the two, the one that is larger. This column is created problem removing duplicates

Answer 1

Two database brand independent options:
option 1:
Select
*
from
Payment_Receive PR
inner join
(select distinct Account_no, Supplier
From Customer where Repid = 100 ) C
on (PR.Account_no = C.Account_no
and PR.Supplier = C.Supplier )
option 2:
Select
*
from
Payment_Receive PR
Where exists
(select *
From Customer C
where
Repid = 100 and
PR.Account_no = C.Account_no and
PR.Supplier = C.Supplier )
with date range:
option 1:
Select
*
from
Payment_Receive PR
inner join
(select distinct Account_no, Supplier
From Customer where Repid = 100 ) C
on (PR.Account_no = C.Account_no
and PR.Supplier = C.Supplier )
where
year(PR.PaymentDate) = 2011 and
month(PR.PaymentDate) = 11
option 2:
Select
*
from
Payment_Receive PR
Where exists
(select *
From Customer C
where
Repid = 100 and
PR.Account_no = C.Account_no and
PR.Supplier = C.Supplier )
and
year(PR.PaymentDate) = 2011 and
month(PR.PaymentDate) = 11

Answer 2

I used a CTE to limit your Customer table, as well as added support for a specific YEAR and MONTH based on your question in a comment.
WITH customersCte AS
(
SELECT id, customer_name, account_no, meter_no, supplier, active, repid
, ROW_NUMBER() OVER (PARTITION BY account_no ORDER BY account_no ASC) AS rowNumber
FROM customers
)
SELECT pr.Account_no, pr.Supplier, pr.Amount_paid, pr.PaymentDate
FROM payments_received AS pr
INNER JOIN customersCte AS c ON pr.account_no = c.account_no
WHERE c.repid = 100
AND c.rowNumber = 1
AND YEAR(pr.PaymentDate) = 2011
AND MONTH(pr.PaymentDate) = 11
