Issues with Dynamic Documents (Arbortext 5.4 & WC9.1)

I've been getting the Arbortext Editor connected to Windchill. I get an error about Dynamic Documents needing auto numbering feature turned on. I have reviewed the TPI on this issue. I have attempted to resolve through Dynamic Document OIR with no luck. Not sure if the issue is client (Arbortext) side or Server (Windchill) side and I realize this may go beyond the usual subject matter for this forum, but if anyone has run into this and solved, I'd sure appreciate some ideas on what to try next.

Thanks!
