Thanks, Jim. Worked like a charm.

Update ALANC/ITEMBL t1
Set UUD1IB = (
Select NEW_THRU
From ALANC/UPDATELIST t2
Where t1.HOUSE = t2.WAREHOUSE And
t1.ITNBR = t2.ITEM)
Where Exists
(Select 1
From ALANC/UPDATELIST t2
Where t1.HOUSE = t2.WAREHOUSE And
t1.ITNBR = t2.ITEM)

You will need a "WHERE EXISTS" clause. See the following thread from the

I need to update a field in a table with the data coming from a
secondary
table.
I have used something like the following in the past to do this.

Update ITEMBL a
Set a.UUD1IB =
(Select Coalesce(Max(b.PAPPRDT),0) As ApprvDate
From PLNREQ b
Where b.PAPPRDT > 0 And
a.ITNBR = b.PITEM And
a.HOUSE = b.PWH)

My problem this time is that I only want to update the ITEMBL record if
there is
a record in the UPDATELIST and the following query fails because not all
the
items in ITEMBL are in the UPDATELIST. How would I modify this query to
update
only the items that are in the UPDATELIST table?

Update ITEMBL t1
Set UUD1IB = (
Select NEW_THRU
From UPDATELIST t2
Where t1.HOUSE = t2.WAREHOUSE And
t1.ITNBR = t2.ITEM)

Any help would be appreciated.
