So why does the sales history in I/M Location History show zero quantity sold for January 2016?
A - If you look at the third entry on the Inventory Transaction Inquiry in your attached screen, you will notice there's an "R" transaction from COP on 1/12/16. It implies that you have a return from customer #383350 for qty 2 in January. Then they are sold on 1/19/16. The return and sold cancel each other. So you have zero quantity sold in the history.
