We are still on GL 8.0

I closed our fiscal year without error and then needed to post a batch to the previous year. After doing so, I saw that amounts posted to balance sheet accounts had an offset to the retained earnings account.

Upon investigation, I discovered that all of the balance sheet accounts in the new fiscal year were changed to income accounts. The old fiscal year is still correct and I am positive that the accounts were correct after the close.

Has this ever happened to anyone else? Is there something that I should beware of or need to change? Don't believe it could be done by an outsider as software is only installed on individual computers and used by myself and two other staff members. They would need to know passwords to sign onto any of our computers, then an id & password for Adagio. Also, what would be the point?

We already have a lot of activity in the new fiscal year so can't restore to pre-closing status but I have two options:

a) do a backup recovery from a couple of days ago and change all the balance sheet account statuses, then post the prior year entry. This is mostly because I can't unpost a prior year batch. I would also have to ensure that any batch posted after I posted the prior year batch is re-keyed and I would have to archive any unposted batches somewhere's that I could retrieve them later.

b) do an entry that just affects the balance sheet accounts impacted (only 2) and the retained earnings.

Which is the better option? The second one seems like a lot less work but I am always concerned that there is something going on in the background that I don't know about.

Or is there another course of action I should be taking?
