On a side note, why does this matter for performance?

This line looks suspicious to me:
and A.artxyr = 2011 || :RPTTXYR
To me too!
For performance issues you should avoid concatenating those things in the SQL statement, calculate the variable value in your RPG and use it as
follows:
MyVar = '2011' + RPTTXYR;
Select ...
Where a.ARTXYR = :MyVar

Hi Dave,
This line looks suspicious to me:
and A.artxyr = 2011 || :RPTTXYR
Are you truly trying to concatenate a number (2011) to a variable? If so, SQL will have to implicitly do some casting to make it work, which might be where the issue is.
The other thing that comes to mind is the FETCH statement -- I'm mainly suspicious of the FETCH because you say it works in iNav, which implies the issue is something you wouldn't have done in iNav (such as a fetch)
It's possible that SQL is implicitly casting between a numeric/character data type in the fetch... maybe because the receiver data type doesn't match the database data type. Worth checking into...

Kurt, Good guess. I still receive the error either way.
Jonathan , You're right it was defined as character. I had great hopes
for this one but still receive the error. I should only need the
coalesce on the Declare statement not the fetch, right?
Tom, the phones are signed numeric and so I tried the + signs. It
seems that a zero shouldn't need to have a sign but it was worth a
shot.
