This is not a fault of IBO. It is the way SQL works.

The expression

(descricao || codigo) the_key

produces a derived field ("expression field", calculate field) that
is dissociated from the underlying fields in your Products table.

If the expression produces unique values, you can make this derived
field a key for your dataset by using the_key as your
Keylinks. However, if you want the set to be a "live dataset"
(updatable) you should include the actual columns in your SQL:

descricao || codigo the_key

In that case, you would set codigo as your Keylinks.
