Hi Eloise,

In Adagio Receivables (just like in Accpac Plus), you cannot remove an invoice until it is completed. In AR, this means either paying it or crediting it. Because you just want to correct the invoice and due dates, you should enter a credit note (using the same date in year 2020) and apply against the invoice, to clear the Current Amount to 0.00. Then if necessary, re-post the invoice using the correct date.

If you want to just change the Due Date of the invoice, then there is an option in the Receivables Company Profile that will allow you to edit the Due Date of posted transactions. I think in your case, this isn't the cleanest way to fix things and you're better off crediting the invoices.
