I checked today's transactions of customers' payments, and you are right that in AR-Q, the customers' check numbers are ALL incorrect. My guess is that DBA is assigning its own sequence of check numbers to the transactions. In AR-Q, the ck numbers were sequenced for example, from 4393 to 4396. These check numbers have no meaning to me and do not reflect the customers' check numbers. ???

I just wanted to confirm your finding.
