OLD GL Date on AR Invoice

For some reason, an invoice created from Project Billing on 9-1-17 transferred successfully to AR but with a date of 9-1-01.  Since we did not have Project billing and AR at that date, the transaction has failed in the Subledger Accounting report with a date of 6-1-04.

Is there a way to get this date corrected without opening the GL period of June 2004?

The AR analyst says the invoice date is not a problem so we do not need to fix anything in Projects or AR.
