Hello Jim,
I found the following in the Tamino documentation:
I would say that, unfortunately, your schema is complex enough to have too many “paths” leading to indexes, which exceeds some limitation in Tamino.
If it would be helpful for you, we could test the schema with an early access version of Tamino 4.1, but perhaps the best approach is that you open an official request with Customer Support.
Cheers,
Trevor.
