We're on 2013 update 8 and able to do similar check number on cash receipt entry with each entry with similar check numbers with same or different customers like "Visa", "Visa1", "Visa3". We've been doing for years but a week ago, it keeps giving an error when updating "Errors have been encountered" and "Out of balance entry was found" Nothing was changed or updated on our system. The only way to make it work is to put check number like 1Visa1, and next V23isa, etc... something that is not similar which is very inconvenient way to do and time consuming. Can anyone help us on how we can fix the way it was?
