COALESCE (DATEPART) Not validating - sql

Question

I'm in the process of validating the following query where my expected result is a row with a revenue value of 0 for any week where there is no revenue to SUM. What I'm getting is only one 0 revenue record where I know there are many. Can someone take a look at my code and see if there is anything obvious I screwed up?
SELECT dbo.LMCustomer.Name,
SUM(dbo.LMDelivery.LdryCensChrg + dbo.LMDelivery.LdryWghtChrg + dbo.LMDelivery.LdryPiecChrg - dbo.LMDelivery.RetnWghtCred - dbo.LMDelivery.RetnPiecCred - dbo.LMDelivery.VrncChrg + dbo.LMDelivery.LdryDelvChrg +

Your query is limited to only show weeks where there is a delivery (and thus, presumably, revenue) by the use of the LMDelivery table in the FROM clause.
If you wished to see a list of all customers, all weeks, and whatever delivery information is necessary, then you're going to need to start with a list of all customers and all weeks.
Assuming SQL Server, you could use a CTE to come up with a list of the weeks that have been in the year so far, connect that with your customer list, then seek out any relevant deliveries and their associated contracts. Something like the following:
;WITH
e1(n) AS
(
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1
), -- 10
e2(n) AS (SELECT ROW_NUMBER() OVER (ORDER BY e1.n) AS n FROM e1 CROSS JOIN e1 AS b), -- 10*10
num(WeekOfYear) AS
(
SELECT
n - 1
FROM e2
WHERE n <= DATEPART(WEEK, GETDATE()) + 1
)
SELECT dbo.LMCustomer.Name,
SUM(dbo.LMDelivery.LdryCensChrg + dbo.LMDelivery.LdryWghtChrg + dbo.LMDelivery.LdryPiecChrg - dbo.LMDelivery.RetnWghtCred - dbo.LMDelivery.RetnPiecCred - dbo.LMDelivery.VrncChrg + dbo.LMDelivery.LdryDelvChrg +
dbo.LMDelivery.PrchChrg + dbo.LMDelivery.LdryPcntChrg + dbo.LMDelivery.AuxpChrg01 + dbo.LMDelivery.AuxpChrg02 + dbo.LMDelivery.AuxpChrg03 + dbo.LMDelivery.AuxpChrg04 + dbo.LMDelivery.AuxpChrg05 + dbo.LMDelivery.AuxpChrg06
+ dbo.LMDelivery.AuxpChrg07 + dbo.LMDelivery.AuxpChrg08 + dbo.LMDelivery.AuxpChrg09 + dbo.LMDelivery.AuxpChrg10 + dbo.LMDelivery.AuxpChrg11 + dbo.LMDelivery.AuxpChrg12 - dbo.LMDelivery.AuxpCred01 - dbo.LMDelivery.AuxpCred02

FROM
dbo.LMCustomer INNER JOIN
num ON 1=1 LEFT JOIN
dbo.LMDelivery ON dbo.LMDelivery.ShipCustRcID = dbo.LMCustomer.RcID LEFT JOIN

(dbo.LMDelivery.UsefCanc = 0) AND (dbo.LMContract.StrtDate >= '2018-01-01') AND (dbo.LMDelivery.LdryDelvDate >= '2018-01-01')
AND COALESCE (DATEPART(week, LMDelivery.LdryDelvDate), 0) = num.WeekOfYear
