I understand the usual approach is to use optimistic buffering. This can be used with local views, too, and it is usually recommended to do so.

The user can do any change; only when trying to save the record will the database server check whether there is a conflict with another user.

Some related commands: CursorSetProp("Buffering"), CurVal(), OldVal().

Saludos, Hilmar.
