Ok, I've got a Purchase Order with 110 lines (two pages 80 and 30).  I've gone through and manually set each "Done" to the correct amount on the Operations tab, and have visited both "pages" of the Initial Demand tab.  I've verified everything on the Additional Info tab as well.  When I try to either "Save" or "Validate" this transaction, I get "The following fields are invalid: Stock Moves."  

I cannot seem to find anyone else having this issue -- any help out there? 

I'm using Odoo 9.0-20151109 on a Bitnami/Amazon EC2 instance.

Thanks in advance,

Seth
