Thank you for a great post. Just one question. The timestamp does only handle "modify". So if for instance a new customer is created the customer does not get a new timestamp - it will be blank. This first happen when the customer is modfied. This means that new customer will not be extracted as the SQL Timestamp will be blank. Of course I can develop something in the export that all customers with a blank SQL Timestamp get's modfied. But is there a more clever solution ? Maybe a parameter to choose that inserts also get a timestamp or something else ?
