Generic delta extractor.

Hi all,

I'm creating a generic delta extractor using a DB view for master data upload. But i dont have any unique date field that i can do delta on. Can i add some field to the extractor which can enable delta to the extractor, like current date etc. If so what fields can i use?

Any help or pointer would be ap[preciated and fully rewarded. Thanks in advance.

Thanks,

Mav.
