We found about 100 postings, all dated 2/4/2024 from year 2017 on our sales ledger. All of them had a zero balance as they have been dealt with back in 2017/18 FY. I am bewildered how these old sales Invoices can suddenly turn up in Myob. It is not even possible to get reports with such old data. Can somebody please enlighten me what could have happened?
