When I run my Inventory Stock Status by Site report and select our 1 of our sites it shows some items having a negative quantity on Purchase Orders. How is this possible? How do I fix it? I have tried going to the Bills where the parts were receipted into inventory and not tying them to a purchase order and it fixes it, BUT when I do that it says the purchase order is still open and that we still have the quantity to receive from the vendor. If I go to the Purchase order and manually close it then the negative quantity comes back onto my report.
