SQL: Left join on calendar table (spark SQL) - sql

Question

I am trying to join data to a calendar table cross joined with user id, to get other columns corresponding to it. I have tried joining on date condition, without the date condition. Created a cross joined master table to left join the other data on. However, seems like I am missing something.
DATE_TBL looks like:
CAL_DT BUYER_ID
2019-03-31 1
2019-03-31 2
2019-03-31 3
2019-03-30 1
2019-03-30 2
2019-03-30 3
2019-03-29 1
2019-03-29 2
2019-03-29 3 ......
DATA2 looks like:
CREATED_DT BUYER_ID ITEM_PRICE
2019-03-31 1 10
2019-03-30 2. 12
2019-03-29 3. 45
2019-03-29 2. 13 ........
Here is my code:
WITH DATE_TBL AS
(
SELECT CAL.CAL_DT, CK.BUYER_ID
FROM DATA1 CAL
CROSS JOIN DATA2 CK
WHERE cal.CAL_DT BETWEEN '2018-01-01' AND '2019-03-31'
AND CK.BYR_CNTRY_ID IN (1,2,3) AND CK.CREATED_DT BETWEEN '2019-03-01' AND '2019-03-31'
GROUP BY 1,2
)
,
REVENUE_CALC AS
(
SELECT CAL.CAL_DT
,CK.BYR_CNTRY_ID
,CK.BUYER_ID
,CK.CREATED_DT AS CREATED_DT
,SUM(CK.ITEM_PRICE) AS ITEM_PRICE
,SUM(CK.QUANTITY) AS QUANTITY
,MAX(COALESCE(I.CURNCY_PLAN_RATE, 1)) AS CURNCY_PLAN_RATE
,SUM(CK.ITEM_PRICE *CK.QUANTITY *I.CURNCY_PLAN_RATE) AS REVENUE
FROM DATE_TBL CAL
LEFT JOIN DATA2 CK
ON CAL.BUYER_ID = CK.BUYER_ID AND CAL.CAL_DT = CK.CREATED_DT
LEFT JOIN DATA3 I
ON I.CURNCY_ID = CK.LSTG_CURNCY_ID
GROUP BY 1,2,3,4
ORDER BY CAL.CAL_DT DESC, CK.BUYER_ID
)
SELECT *
FROM REVENUE_CALC
Desired Result Must look like:
CAL_DT BUYER_ID ITEM ITEM_PRICE
2019-03-31 1. 10
2019-03-31 2. null
2019-03-31 3. null
2019-03-30 1. null
2019-03-30 2. 12
2019-03-30 3. null
2019-03-29 1. null
2019-03-29 2. 13
2019-03-29 3. 45......
What I get is only the data for common dates. Could someone help me understand what I am doing wrong?
