This shows that the client was using their Order Entry module and the option was deselected in the company profile to allow quantity to go below zero and a staff was able to still ship items even though the quantity was at zero and at times not enough to accommodate the ship amount.

I tried this on my stand alone laptop but the message to notify me that the stock was not enough came up and I was not able to move past it unless I changed the quantity or item all together.

Not sure why it happened for the client.
