Request for Alternative Methods to Correct Future-Dated Invoices in Oracle AR

Hello, We have a situation where several invoices were created, completed, and accounted for in Accounts Receivable (AR) with future dates—more than a year out. According to our understanding, these invoices cannot be deleted directly in Oracle since they are already accounted. Is there any supported method or alternative approach to address or remove these future-dated invoices, other than handling them through manual adjustments? Thank you for your assistance. Best regards, Tushar Rana
