I am trying to identify a list of BusinessUnitID which are in the
first query but not the second. The below doesnt quite work?
Thanks in advance

select distinct BusinessUnitID from S_IS_BU b inner join BIProd.dbo.D_BusinessUnits c on b.BUKey = c.BUKey where c.Year = '2011'

where not exists
(select distinct BusinessUnitID from Upload_GeneralExpense )

This will give you the BusinessUnitIDs from S_IS_BU (I am assuming that's where it comes from) that can be found in the intersection of S_IS_BU and BIProd.dbo.D_BusinessUnits based on the BUKey, but don't exist in the Upload_GeneralExpense table

select distinct BusinessUnitID
from S_IS_BU b inner join
BIProd.dbo.D_BusinessUnits c
on b.BUKey = c.BUKey
where c.Year = '2011'
and not exists
(select *
from Upload_GeneralExpense u
where b.BusinessUnitID = u.BusinessUnitID
)

For example:

SELECT DISTINCT
BusinessUnitID
FROM S_IS_BU b
INNER JOIN BIProd.dbo.D_BusinessUnits c
ON b.BUKey = c.BUKey
LEFT OUTER JOIN Upload_GeneralExpense u
ON b.BusinessUnitID = u.BusinessUnitID
WHERE c.Year = '2011'
AND u.BusinessUnitID IS NULL
