Procedimento de Bloqueio atraso

estou com uma procedure , que analise se o cliente do pedido esta em atraso, caso sim ele vai para uma autorização... o grande problema é que , mesmo que o cliente esteja sem nenhum titulo em atraso, mas já houve alguma vez registro de que ele atrasou ele traz... gostaria de consertar para ele ir para autorização só e somente só ele estiver em atraso mesmo...
