>>>The above approach looks like what I do in the VFP application. But I don't think you can't update SQL Server tables using TableUpdate(). And I don't use remote views in this application, so I don't see how TableUpdate would work there. Unless I am misunderstanding something.

>>You can take a cursor and make it into an updateable remote view just by setting the correct cursorsetprop settings.

>That's an interesting approach. I will think/try this. Thank you very much.
