You cannot archive check batches in AP.

If you have Adagio Ledger 9.0A or later, you can post the AP checks and then retrieve them into GL into the appropriate fiscal year.

You may want to contact your Adagio consultant to make sure you are performing the correct steps in regards to your place in the year end cycle, and not posting batches when they should not be, etc.

You could also check out our Previously recorded webinar on Year End Processing in Adagio, to see what type of processing is required, including the soft-year end capabilities of Adagio Ledger and how that works with AP and AR.
