[SOLVED] DQS Representative Creator

The online help for the Representative Creator is rather sparse. I am trying to use it with output from Extended Unification. I started with tutorial 09 match and merge. My question has to do with the Selection Rules. I have found some records in the input group missing certain key attributes, so I added a selection rule with the acceptance condition for those attributes set to is not null. However, it seems this acceptance condition is not working since the merge output still contains representatives missing the key attributes. Does anyone know how the selection rules are supposed to work? A fully configured documented sample of this step would go a long way towards making it more user-friendly.

Thanks

Hi CanMan,
selection rules work like an "order by" in SQL. for example: if you use following three selection rules

1)Meta_last_updates Descending
2)sco_name Ascending
3)sco_instance Ascending

and one acceptance condition i.e. name is not null

the result will be equivalent to the following statement in SQL

Select Top 1 name from xxx
Where name is not null -- Acceptance Condition limit the results
Order by Meta_last_updates desc, sco_name asc, sco_instance asc --Selection rules sort the results

In other words your latest name value from the group will be selected for the golden record.

Hope this helps.
regards,
Jikku

You definitely aren't a newbie anymore in my mind. 3 years is a lot of experience...

You can post techniques using [SHARING] in your title to brag about how you have solved difficult scenario's to help others and generate more DQS threads
