If the order has already been Placed, only the Date and Description can be edited. If other changes need to be made, the order will need to be deleted and re-entered.
If the order has already been Received into your inventory (or is a Direct Ship or Guest Checkout), only the totals can be adjusted. If quantity adjustments need to be made, see Edit Physical Count Directly On the Product List.
Option 1
Double-click on the order to edit the totals. When finished, click 
OK to save and close the form.

- Click Edit, and select Received Orders from the drop-down menu option to place the Inventory Orders grid into edit mode. Changes made will automatically be saved when tabbing out of each grid cell.
- To close out of the edit mode, click Edit, then uncheck Received Orders or just close the Inventory Orders form to reset automatically.
