Native RI builder allows to insert NULLs. At least in VFP8 it does. Basically, it gives an error on SEEK command, which is handled in rierror routine and as the end result returns true.

I'm currently writing my own RI builder where I'll try to avoid things which are not allowed in the Ole Db. Do you have link handy?

Thanks again.
If it's not broken, fix it until it is.
