When on a purchase order, you will see a bug icon just to the right of the item number. When you click on this, a pop-up box will appear where you can select a part exception. Part exceptions can be created and deleted within the admin editors.

Here are the defaults that you will have:

1. Back Order: The part is back-ordered and will show that information on the item within the purchase order.
2. Discontinued: The part has been discontinued by the vendor. This will set the quantity on the purchase order and invoice to 0.
3. Substitution: The original part ordered has been superseded. This will allow you to take the supersed part and replace the old part on the purchase order and on the sales orders.
4. MinQtyOverride: There is a minimum amount to be ordered of the item and the current order qty is less than the minimum. This will update the item's package quantity and if the part is a special order, update the quantity on the sales order.
5. MinQtyStop: There is a minimum order quantity for the item but the quantity ordered is less than the minimum. This will set the order quantity on the purchase order to 0.
6. Administrative: This stops the order of the item due to administrative reasons. The item's order quantity on the purchase order will be set to 0.
