I need help combining two queries in SQL Server 2008

Hi experts,
I need your assistance combining the two queries below.
I need to take the sum of query #1 and subtract the sum of query #2 from it.
How can I do this? I have listed both my queries below.

NOTE: The PONUMBER field in query 1 matches the PONUMBER field in query #2.

--Query 1
SELECT 
  SUM(I.[QTYORDER])
  FROM POPHEADER as I
  inner join POPDETAIL as P
  on I.PONUMBER = P.PONUMBER
  where I.[POLNESTA] not in (4,5,6) and P.[DOCDATE] >= '1/1/2014' and I.[ITEMNMBR] = '209822011'
  and I.POTYPE =1
  
--Query 2
SELECT SUM(QTYRECVD) AS QTY
     FROM INVOICE_TABLE
where [DATERECD] >= '1/1/2014' and RCPTSOLD = 0
and  [PONUMBER] = '07277' and [ITEMNMBR] =  '209822011'

Thanks in advance,

Well, your second query only contains PONUMBER = '07277', so you just could do this:

SELECT  SUM(I.[QTYORDER])
FROM    POPHEADER AS I
        INNER JOIN POPDETAIL AS P ON I.PONUMBER = P.PONUMBER
WHERE   I.[POLNESTA] NOT IN (4, 5, 6)
        AND P.[DOCDATE] >= '1/1/2014'
        AND I.[ITEMNMBR] = '209822011'
        AND I.POTYPE = 1
	AND i.PONUMBER <> '07277'

But I get the feeling you are looking for something more than that, so perhaps this:

--Query 1
SELECT  SUM(I.[QTYORDER])
FROM    POPHEADER AS I
        INNER JOIN POPDETAIL AS P ON I.PONUMBER = P.PONUMBER
        LEFT JOIN (SELECT   PONUMBER
                   FROM     INVOICE_TABLE
                   WHERE    [DATERECD] >= '1/1/2014'
                            AND RCPTSOLD = 0
                            --AND [PONUMBER] = '07277'
                            AND [ITEMNMBR] = '209822011'
                   GROUP BY PONUMBER
                  ) d ON i.PONUMBER = d.PONUMBER
WHERE   I.[POLNESTA] NOT IN (4, 5, 6)
        AND P.[DOCDATE] >= '1/1/2014'
        AND I.[ITEMNMBR] = '209822011'
        AND I.POTYPE = 1
        AND d.PONUMBER IS NULL

Ah, never mind, it looks like I misread the question.
