A customer posted a receipt in 2009 and applied it to two invoices. Now, in 2010, she would like to change how the receipt was applied ("unapply" one of the invoices, and apply another instead). Is there a way to make a change in a receipt that is in history? And I don't know if this is important to mention, but there was also an unapplied amount from this receipt in question.
Please advise.
