To my knowledge TD transitive closure rules have never been clearly described. It might have to do with trade secrets or whatever. So, some tweaking of a "strange" query could be necessary to see what exactly fails in the closure.

I would be interested to see whether changing this group of conditions will make any difference:

          >         AND     a14.PromoID > 0
          >         AND     a12.corpid  IN ( 1 )
          >         AND     a13.Family_ID  IN ( 1, 10 ) =

Try to make them equalities. If the query becomes as fast as you expect it then relax the conditions one by one until you find the true reason of the problem here.

The rest of the query looks just fine for the transitive closure to be used. But inequalities and (hidden) OR conditions - less certainty there.

Out of interest ... Which tense is mainly used in the article you are referring to? Present or future? If future, then it is a technical article about some *future* release. If present, it is just a marketing article.
