Depending on the state of a Purchase Order (PO), you'll have a few options to delete, cancel, or force complete a PO.
Overall, Drafted POs can be deleted, while POs in a "Created" status can be cancelled. Keep reading for more information:
Deleting a PO
Only POs in a "drafted" status can be deleted.
If the PO is in a draft status, you'll see a red "delete" button in the lower left corner as seen below:
Once a PO has left the drafted status (Open, Partially received, Overdue, Complete, Canceled), it cannot be deleted.
Canceling a PO
Only POs in an "open" or "overdue" status can be cancelled.
If the PO is in an open or overdue status, you'll see a red "cancel order" button in the lower left corner as shown here:
Force Completing a PO
If some units from a PO have been received (but not all of them), this will be put into the "Partial" or "partially received" status.
To cancel that order and not receive any more products, you'll see the option to "Force Complete" instead. This means no further quantities will be accepted on this PO. It will not undo any previous additions to the inventory.
Once a PO or products have been received, there is no way to undo those additions within the POs feature. Any changes must be done manually from the Inventory page (using the Actions button), the Product detail page (under Locations), a Stocktake, or the Barcode Scanner Mobile App.
