The updateSet class requires for append() completely identical table structures of the source and destination, that's the first I come to think about. Quote OLH: "If the table structures are not exact matches, append( ) will terminate when it encounters the discrepency." End of quote. And it does terminate without giving you an error. Then there are some more tricky points, like rows that would cause a key violation and others ... if you got a copy of Ken's book, there you will find quite a great lot of sample code and detailed explanations about it. Hope I could help, Heinz
