Back in 2004 while we were still using AccPac, someone somehow managed to change the date on their system to 2020 and then entered 2 credit notes into the year 2020. We had Adagio installed in 2008 and the credit notes remain on our system showing in the year 2020. Even though the amounts of the credit notes from 2020 were applied to the original invoices from 2004 and it showed the balance on the customers accounts as ZERO, the amount from the invoice in 2004 continued to show up as an outstanding amount owing on the customers statements every month because the statements did not recognize the Credit Note amount in 2020.

In an attempt to resolve this, we entered a Credit Note into the current date to offset the old invoice and added an Invoice in 2020 to offset the Credit note in 2020. This resolved the statement problem, but now the customers account shows a credit balance because of the credit note in current, but AR doesn't even see the invoice from 2020. I suppose it's because we haven't done a day end in 2020? If I went into OE on the date of the invoice in 2020 and ran a day end, would I cause other problems? Would it move all our current OE to history?

I can't think of any other way to get this resolved unless there is a way to delete invoices and credits at least temporarily to get rid of the invoices and credits in 2020 altogether. Or edit the date on the invoices and credit notes. Is there a way to do this?
