As far as I've understood, this solution requires enabling change tracking in SOURCE Database. Right?
If so, unfortunately it is in most scenarios not applicable and therefore this pattern will be useless. In serious environments one can just forget modifying ERP (or any other heavy OLTP Datasource) tables and set the change tracking on. In such cases, the classical anchor based incremental loading pattern is still the best way.
Thanks for the information anyway.
