I regularly have to change account codes on sales invoices and up until this month I have been able to do this no problem. Has MYOB had an update? Now I cannot edit/change the account numbers. Has anyone encounted this problem and know how to do it now?
There has been no change to the way in which users can update account codes on invoices. I would say that if you are unable to do so, I would recommend checking the following: Setup>>Preferences>>Security -- Transactions Can't be Changed, They must be Reversed. If that is enabled those transactions can't be changed.
If that is not enabled, go check the Sales Register for that transaction is that transaction got a blue or grey arrow? I would assume a grey arrow indicating that the transaction is locked and not editable. Typically, you see this for transactions recorded in a previous financial year or a secondary transaction (a Bank Deposit, Electronic Payment...) is involved or potentially a user access issue.
