Quick question. Someone cancelled - NOT closed - a Sales Order (which I know cannot be undone, correct?) while a Purchase Order associated with it was in a state that triggers a flow. Now we can't get the Purchase order to stop triggering the flow, because attempting to save any changes on the PO results in

The Sales Order has been set to 'Pending Approval' so this Purchase Order can't be created.

Is there any way short of deleting the entire purchase order transaction (if it'll even allow us to do that) to make a change on the purchase order now that the Sales Order is marked as cancelled?
