using CTE while declaring variables in SQL - sql

Question

I have two decraed variables and I am trying to set the values from the result of my CTE,
declare #Total_new_claims_received int
declare #Total_Claims_Processed int
End solution I'm looking for is being able to set both declared values from CTE results:
select #Total_new_claims_received = count(id)
from cte
where benefit_code_id not in ('739')
select #Total_Claims_Processed = count(id)
from cte2
where benefit_code_id not in ('739')
Current Code:
declare #Total_new_claims_received int
declare #Total_Claims_Processed int
with cte (ID, Date)
as (
select c.id, c.date
from axiscore.dbo.claim c with (nolock)
inner join claim_line cl on c.Claim_ID = cl.Claim_ID and cl.Linenum = 1
left join axiscore.dbo.member_policy mp with (nolock) on c.Member_Policy_ID = mp.Member_Policy_ID
left join axiscore.dbo.policy p with (nolock) on mp.policy_id = p.policy_id
inner join axiscore.dbo.Claim_Status s with (nolock) on c.Claim_Status_ID = s.Claim_Status_ID
left outer join axiscore.dbo.Claim_Reason_Type r with (nolock) on c.Claim_Reason_Type_ID = r.Claim_Reason_Type_ID
where
c.Updated_Date between '10-1-2019' and '10-31-2019'
and p.Payor_ID = 8
and (c.Claim_Status_ID <> 8)),
cte2 (ID, Date)
as
(
select c.id, c.date
from axiscore.dbo.claim c with (nolock)
inner join claim_line cl on c.Claim_ID = cl.Claim_ID and cl.Linenum = 1
left join axiscore.dbo.member_policy mp with (nolock) on c.Member_Policy_ID = mp.Member_Policy_ID
left join axiscore.dbo.policy p with (nolock) on mp.policy_id = p.policy_id
inner join axiscore.dbo.Claim_Status s with (nolock) on c.Claim_Status_ID = s.Claim_Status_ID
left outer join axiscore.dbo.Claim_Reason_Type r with (nolock) on c.Claim_Reason_Type_ID = r.Claim_Reason_Type_ID
where
c.Updated_Date between '10-1-2019' and '10-31-2019'
and p.Payor_ID = 8
and (c.Claim_Status_ID in (7,6))
and (c.Claim_Reason_Type_ID not in (136,137)))
select #Total_new_claims_received = count(id)
from cte
where benefit_code_id not in ('739')
select #Total_Claims_Processed = count(id)
from cte2
where benefit_code_id not in ('739')
Currently,
it's only setting the value for Total_new_claims_received. It errors out on the second select when I'm setting the value for Total_Claims_Processed. The error is 'invalid object name 'cte2'.
I'm using CTE instead of temp tables becuase I'm calling this proc in a SSIS package. SSIS package doesn't do well with Temp tables. Any other ideas welcome as well.
thanks for your time!

From WITH common_table_expression (Transact-SQL):
A CTE must be followed by a single SELECT, INSERT, UPDATE, or
DELETE statement that references some or all the CTE columns
So define each of your CTEs before each of the select statements that uses it:
declare #Total_new_claims_received int
declare #Total_Claims_Processed int
with cte (ID, Date) as (
select c.id, c.date
from axiscore.dbo.claim c with (nolock)
inner join claim_line cl on c.Claim_ID = cl.Claim_ID and cl.Linenum = 1
left join axiscore.dbo.member_policy mp with (nolock) on c.Member_Policy_ID = mp.Member_Policy_ID
left join axiscore.dbo.policy p with (nolock) on mp.policy_id = p.policy_id
inner join axiscore.dbo.Claim_Status s with (nolock) on c.Claim_Status_ID = s.Claim_Status_ID
left outer join axiscore.dbo.Claim_Reason_Type r with (nolock) on c.Claim_Reason_Type_ID = r.Claim_Reason_Type_ID
where
c.Updated_Date between '10-1-2019' and '10-31-2019'
and p.Payor_ID = 8
and (c.Claim_Status_ID <> 8)
)
select #Total_new_claims_received = count(id)
from cte
where benefit_code_id not in ('739');
with cte2 (ID, Date) as (
select c.id, c.date
from axiscore.dbo.claim c with (nolock)
inner join claim_line cl on c.Claim_ID = cl.Claim_ID and cl.Linenum = 1
left join axiscore.dbo.member_policy mp with (nolock) on c.Member_Policy_ID = mp.Member_Policy_ID
left join axiscore.dbo.policy p with (nolock) on mp.policy_id = p.policy_id
inner join axiscore.dbo.Claim_Status s with (nolock) on c.Claim_Status_ID = s.Claim_Status_ID
left outer join axiscore.dbo.Claim_Reason_Type r with (nolock) on c.Claim_Reason_Type_ID = r.Claim_Reason_Type_ID
where
c.Updated_Date between '10-1-2019' and '10-31-2019'
and p.Payor_ID = 8
and (c.Claim_Status_ID in (7,6))
and (c.Claim_Reason_Type_ID not in (136,137))
)
select #Total_Claims_Processed = count(id)
from cte2
where benefit_code_id not in ('739');
