Cancel Delivery Order errors
Delivery orders that could not be cancelled after the order was cancelled.
Open Cancel Delivery Order Error
The link opens the screen directly in the Integration Dashboard.
The main cause: it is already validated
A validated delivery order means the goods have actually left your stock. Odoo does not simply cancel that — it needs a return.
The fix: create a return in Odoo
Open the delivery order in Odoo and use the Return button to bring the goods back into stock, then delete the error row from this screen.
Other causes
A linked posted invoice.
Insufficient rights to cancel stock operations.
Check your balances afterwards
Delivery cancellation errors leave stock balances affected. After resolving them, review the affected products' stock in Odoo.
Retry once the cause is fixed
Fix the cause first, in Odoo or in your settings, then press Retry on the row. Retrying without fixing the cause fails with the same message.
