Reconciling A/P to G/L

How does one go about reconciling A/P to the General Ledger. In the simplist form of the question, wouldn't the open invoice total equal the G/L A/P account balance? If I run AP230, that will give me open invoices as of the run date. But I need open invoices as of year end date (putting the cut-off date in only looks at invoices with that date or prior, not OPEN invoices as of that date). It would seem to be a simple task but I'm unable to determine how to go about it.
