I'm using Ledger ver 9.0B and we are in the middle of year end and have started the new year. I ran the data integrity check and it reports a batch control error. So I used the rebuild and all the "next year" batches disappeared. It appears to be running fine otherwise. I've restored from a backup but data integrity check still reports a batch control error. I don't know whether to do a rebuild again or let it go? And if I do a rebuild what is the best way to preserve my batches?
