Invoices with incorrect dates

Hi Team,

Please share your inputs. Thanks a lot  in Advance

We have a few invoices issued recently with incorrect dates. No invoices should ever be issued through the system with a date prior to its generation – this throws off our aging and accuracy when reporting accounts receivable. Here are the examples – this happens infrequently, but has happened for many years. In normal cases where there’s a one-off situation, I will incomplete the invoice prior to posting it to the GL and update the date manually, but these were posted before I could so now they’re locked in.
