If this means that the temp tables have NUPIs then I would suspect data skewing( like a high occurrence of NULL or default (0 or blank )), or more likely a valid BAN value that occurs many times in each table. Try a select BAN, count(*) from each table order by 2 desc having count(*) GT 100 (or a 1000); to see if this is an issue.
