You suggest that the simple act of re-sorting the item list will now allow me to import Inventory Parts?  I tried it and as I suspected, it did not work.  I still get the error.  I have attached screen shots of the error and of my mappings.

It seems like a catch-22.  I cant import my items because I do not have UOM set on.  But I cannot set UOM on because I have the PRO version of Quickbooks.  Therefore I cannot import Inventory Parts into the Pro version.  Again, this sounds like a bug of some sort.

Surely someone has done this successfully.
