"I made a mistake. I've issued credit note 502401007, this should have been cancelled afterwards (inv.502401027) as I should have related to another invoice -> therefore CN 502401026 has been issued.
Then suddenly India has asked us to stop all credit notes and cancel them. I made a mistake when cancelling CN 502401007 again, although this has been done already. So document 502401059 from 20.08.2013 would have to be cancelled again. then the account should be settled"
Hope it helps.
