I have no more responses. We've gone round on this too many times; you say "RDM creates NULLs" and I say "no it doesn't, missing information isn't the same thing as NULLs." Then you say "RDM creates NULLs" and it starts anew. I'm done, as I'm getting nowhere, and getting no information on which to determine where to go.
