QS: undup VS undup independent
Posted: Wed Feb 22, 2006 6:20 am
Hi all.
In my experience the "undup" type of match ha some limitations:
1) groups created in a pass are not merged in the next passes
2) only master records and residuals are made available for
the subsequent passes
Undup independent seems to solve those limitations. To enter in a group I think it's enough that at least one of the match criteria expressed as a pass is matched, and this match doesn't need to be with the master record but it also can be with whichever of the records in the group.
The problmem with undup independent is that I don't know to which pass is related the weigth (I see in the extract file), because all the records in the group have the same pass number.
My question is: how can I know more about undup independent ?
How can I work with cut-offs ?
Thanks
