No matter how tempting the idea of 'moving the order' sounds... please consider processing the document all over again in your production company.
There is literraly too much at stake. As you mentioned in your post, everything must match... not just the Vendotr No and the item references. Also the Lot#, Exp. Dates, Bin Codes...
You will invest more time in setting up the COnf Pack and inject a lot of uncertainty in prcessing it.
I propose a head-to-head competition: have someone set up the conf pack... have another user manually process the document.
I know where to place my bet.
