Kevin;

I agree with Eric. Pulling 200,000 records over a network is not something I would do! Even on a local box this would take time! Just what has to be displayed by loading this data? Perhaps we can give some design suggestions to help speed up the process?

Is it one store or many? Do you lookup by product/store or just display everything?
