Stock quantity adjustments from within a sale
Whilst in a sales order or sale shipment that has a status of Open (the status cannot be any other status), you can stock adjust lines of products.
When in a Sale (whether it be an order or a shipment that has a status of open)
Select which lines of products need stock adjustments done (use the Ctrl button on your keyboard and use the mouse to select the product lines)
Right click on your mouse and hover it over New
Further options open
Click on Stock Adjustments
A new stock adjustment window opens which automatically adds in all product lines selected from the previous sales window
Change the quantities if required (it automatically defaults the quantity as the quantity ordered from the sales order/shipment)
Select a reason for the adjustment
Click on button Finalise
(Note: save will not action the stock quantity adjustment, it will only save what you've done so far on it. Finalise is what affects the stock on hand)
