SAGE - transaction entered after year end closure

Can anyone help?  I have taken over as bookkeeper for a client.  They are using Sage 50 with the CIS module.  The year end has been run and then numerous transactions have been posted into that year after it is closed.  How can I best pull out the information for the accountant to prepare the accounts?  My thoughts to date have been that I should run a trial balance at the year end, as well as a b/fwd trial balance.  I could then look at the transaction references of the year end journal, and pull our all of the entries date within the previous year, but with a transaction reference after the year end journal.  These transactions should agree to the b/fwd trial balance - shouldn't they?

Any other ideas / advice very welcome!

Thanks.
