When recoding an invoice for an adjusting journal entry, the Accounting Date field should not be auto filled because users will not notice this new box and hit submit not knowing that they created an adjusting journal entry with the same date as the invoice date. By not having it filled it will force users to actually set a date they want for the journal entry. Maybe also have a yellow Exclamation mark ! next to the box explaining that it will be the date of the adjusting journal entry.
