Returning LINE with no inner join match - sql

Question

I am trying to put a statement together the first part of the code works.
DECLARE #FYEND date, #YTD date, #PYTD date, #Openmonth date, #Monthtodatefrom date, #Monthtodateto date, #Priormonthdatefrom date, #Priormonthdateto date, #Currentmonth date
SET #FYEND = Dateadd(year,1,DATEADD(year,DATEDIFF(month,'19010701', getdate() ) /12,'19010701'))
SET #YTD = GETDATE()
SET #PYTD = DATEADD(YEAR,-1,#YTD)
SET #Openmonth = dateadd(DAY,1,dateadd(YEAR,-1,EOMONTH(#YTD,-1)))
SET #Monthtodatefrom = EOMONTH(getdate(),-2)
SET #Monthtodateto = Dateadd(DAY,1,eomonth(#ytd,-1))
SET #Priormonthdatefrom= DATEADD(YEAR,-1,#monthtodatefrom)
SET #Priormonthdateto= dateadd(year,-1,Dateadd(DAY,1,eomonth(#ytd,-1)))
SET #Currentmonth=dateadd(DAY,1,EOMONTH(getdate(),-1))
SELECT
b.T3,
b.Country_name,
b.Division_Name,
b.SHOP_NAME,
b.Shop_Type,
b.MTD_Result
FROM
(
SELECT
a.T3,
a.Country_name,
a.Division_Name,
a.SHOP_NAME,
a.Shop_Type,
sum(case when coa.EBIT in ('EBIT') then gl.Amount ELSE 0 END) as MTD_Result
FROM
(
SELECT
s.T3,
s.DIVISION_NAME as Division_Name,
s.SHOP_NAME,
s.COUNTRY_NAME as Country_name,
s.[Business Grouping] as Shop_Type
FROM Finance_PRD.dbo.Shops s
WHERE
s.DIVISION_NAME in ('NSWACT FCB Retail North', 'NSWACT FCB Retail South', 'Vicmania', 'The Heartland', 'SA FCB Retail', 'WANT FCB Retail', 'UT Leisure', 'TA Leisure', 'Contact Centre')
and s.BUSTYPE='ARET'
and s.[Open Date] < #Currentmonth
and s.[Close Date] is null
and s.T3 = '497088'
GROUP BY
s.T3,
s.SHOP_TYPE,
s.PRIMARY_STORE_T3,
s.DIVISION_NAME,
s.t3,
s.SHOP_NAME,
s.COUNTRY_NAME,
s.[Business Grouping],
s.BUSINESS_GROUPING_NAME,
s.SHOP_NAME) a
INNER JOIN Finance_PRD.ANZ.ConsolidatedAUD as gl
on a.T3 = gl.T3
INNER JOIN Finance_PRD.dbo.ChartOfAccounts coa
on gl.AccountCode = coa.Code
WHERE gl.Period > CASE WHEN MONTH(#Monthtodatefrom) <= 6 THEN
CONCAT(YEAR(#Monthtodatefrom), RIGHT(CONCAT('000', MONTH(#Monthtodatefrom) + 6), 3))
ELSE CONCAT(YEAR(#Monthtodatefrom) + 1, RIGHT(CONCAT('000', MONTH(#Monthtodatefrom) - 6), 3))
END and gl.Period < CASE WHEN MONTH(#Monthtodateto) <= 6 THEN
CONCAT(YEAR(#Monthtodateto), RIGHT(CONCAT('000', MONTH(#Monthtodateto) + 6), 3))
ELSE CONCAT(YEAR(#Monthtodateto) + 1, RIGHT(CONCAT('000', MONTH(#Monthtodateto) - 6), 3))
END
GROUP BY
a.T3,
a.Country_name,
a.Division_Name,
a.SHOP_NAME,
a.Shop_Type
)b
but when I want to join on a second statement it does not return a value, I require the second statement to be 0 if there is no join.
Second part of the code is here which I set below query b
Inner join Finance_PRD.ANZ.ConsolidatedAUD as gl
on b.T3 = gl.T3
Inner JOIN Finance_PRD.dbo.ChartOfAccounts coa
on gl.AccountCode = coa.Code
WHERE gl.Period > CASE WHEN MONTH(#Priormonthdatefrom) <= 6 THEN
CONCAT(YEAR(#Priormonthdatefrom), RIGHT(CONCAT('000', MONTH(#Priormonthdatefrom) + 6), 3))
ELSE CONCAT(YEAR(#Priormonthdatefrom) + 1, RIGHT(CONCAT('000', MONTH(#Priormonthdatefrom) - 6), 3))
END and gl.Period < CASE WHEN MONTH(#Priormonthdateto) <= 6 THEN
CONCAT(YEAR(#Priormonthdateto), RIGHT(CONCAT('000', MONTH(#Priormonthdateto) + 6), 3))
ELSE CONCAT(YEAR(#Priormonthdateto) + 1, RIGHT(CONCAT('000', MONTH(#Priormonthdateto) - 6), 3))
END
I've tried to understand all the different joins and even attempted to use is null, if and coalesce to no avail.
