If a sales order is cancelled, any reserved sales items on that order will have the reservation removed, adding that reserved quantity back into the quantity on hand total.

We now have three sales orders for this product, all at a status of ‘Confirmed’:
Clicking on the Order Number link above will open that order.
Order Screen Details
Opening the 3 orders created above, we can see that the ‘in stock’ quantity of the 3 orders reflects the ‘in stock’ quantity presented when the order was placed.
The first Sales Order AZJ001244-SI shows 20 IN STOCK for the item:
The third Sales Order AZJ001245-SI is showing 12 fewer
The orders can be picked and packed in any order, however order J03017-SI will only allow 3 to be picked, while the outstanding 4 would be placed on backorder.
So, how do you manage a situation where your customer calls and says that order J03017-SI must go out urgently, and order J03015-SI can be put partially on backorder instead?
To achieve this, you must first ‘Release’ some of the reservations for preceding orders.
Click the ‘View Outstanding Requests’ under the item to be picked:
This opens the items ‘Transaction’ screen, filtered to show current outstanding ‘Pick Requests’:
The Pick Requests can be ‘excluded’ by clicking the orange ‘Exclude’ button.
In order to be able to pick this order, I can exclude either order J03015-SI or J03016-SI.
Either of them will release enough stock to enable J03017-SI to be picked.
In this case I exclude order J03015-SI:
Back to the pick screen for J03017-SI, refresh to update the ‘in stock’ quantity.
The 5 released above are added to the 3 in stock, allowing the order to be picked in full:
Reviewing what is happening here, we can now pick the last order in – J03017-SI.
We could always pick order J03016-SI, though it now shows 13 in stock (the other 7 being reserved for J03017-SI):
While the order we excluded from the pick requests is left with 1 available to pick:
Pick order J03017-SI for 12 and the order status changes to ‘Packed’…
This leaves ‘1’ un-reserved in stock.
In order to reserve that one against the order we ‘Excluded’ previously, we need to re-open the ‘Outstanding Transactions’ again (from ANY order with this product on it).
We see that the ‘Pick Request’ for order J03017-SI no longer appears as it has been fully picked.
Click the ‘Include’ button to change it to reserve any available stock against that order.
Because we have used stock that was reserved for J03015-SI to pick J03017-SI, there is insufficient quantity in stock to pick J03015-SI.
However, we can ‘exclude’ J03016-SI in order to release some stock to J03015-SI.
Change the order status to ‘Packed’ which will evoke the ‘Back Order’ process to place the outstanding quantity on backorder.
