When implementing this kind of business rule I'd need the option to specify a percentage, not just an absolute value. I would focus on trying to put the data required to make this kind of determination into a place where applications implementing such business rules and monitoring can readily get at it. The "ERRORS TO" and maybe a corresponding "STATS TO" option where a table can be specified for the system to place the problematic data and stats about the copy itself. David J.
