It happened one time last month. It happened again yesterday. The shipping 
dept fulfilled a SO without any problem and shipped it out. But the fulfilled 
qty changed back to 0 even you post it. So, the finance dept cannot create an 
invoice for this SO.
We passed this case to a consultant firm and they couldn't find the problem, 
either.
So, we voided the SO, created a new SO, fulfilled it, and it is fine this 
time. Does any one have an idea how/why GP change the fulfilled qty back to 0?
Thanks for your attention and help.

I can't answer the question about why it would change on its own, but if you 
run the utility to Reconcile Sales Documents does it change the fulfillment 
qty back? Are your Inventory quantity records changed?
