Fortunately, with Ledger V9.0A, you won't have to archive and retrieve next year's batches any more. You can just "open" the new year and keep on processing. We are planning webinars all next week to demonstrate the new features.

I'm curious how the program would "know" how to renumber the reference field when a batch is being retrieved. While this suggestion has come up several times, every user has been setting the reference differently. What would make sense to you?
