I have questions regarding open items: for annual financial statements we need an open items list. It has to show all outstanding customer payments not yet having been paid, even if closed after this date.
If the path ‘open bill’ - ‘payment’ - ‘external payment’ is chosen, there`s no way either to give in past payment dates. It follows that the accounting ledger report shows items as unpaid as long as ‘external payment’ is done, no matter what the real payment date was.
