It's hard to say without seeing the definition of the logicals as well as the SEQUEL view. Have you checked with ASC?

It's not just SEQUEL. Look at your ORDER BY clause. You can contact me

Thanks for your offer Paul. My ORDER BY contains a field (trailer #) from the file I've added to the join. There are logicals using this as the most significant subkey, but they all have select/omit criteria as well. Does this mean they won't be considered by the optimizer?
