Hi Kev,

The answer is rhusmore. When you use a view ( with NODATA ) VFP try to optimize the SQL and load portion of the index file.

There are a lot of threads about the use of unbalanced index like ( deleted index ) and the impact on the network traffic .

You are able to use SMS to see the network traffic and optimize your application. I do this to run my application on a 4MB Token Ring corporate network.
