Two summary lists come out of it, and they are different problems: - **Unreconciled**: a real difference. Something is missing, duplicated or mis-dated. Work these. - **Unchecked**: no statement for that account-month. Get the statement, or record why it does not exist. ## Working a difference Look in this order, because this is roughly the frequency order:
