Hi everyone,
Ive just started looking at the Fuzzy Lookup feature and i think i must be getting something fundamentally wrong. I have two tables - each contain different meta data representations for a set of potentially similar documents. The only chance i have of matching a document in table A to a document in table B is a common title field. However, manual input means that the titles may differ in both tables although they are potentially quite similar in most cases.
In the lookup i get to specify the output columns from table B (Reference) which is fine, but i don't seem to get to choose the columns from table A that i would also like to see. So my output shows me all the documents from table B that it thinks are similar to ones in table A...but not identifying which record it's similar to.
I initially thought that the "pass through" columns that i identified would appear in the output - but this does not seem to be the case.
I must be using it incorrectly, but i have no idea how to progress with this apart from creating a new source table (C) which is a full outer join of table A and B - and then also using table C as the reference table, but that seems madness.
any help would be appreciated - ta

I may have spoken too soon.
It's strange, but if i've been using the 'Advanced Edit' dialog to setup the lookup - which i had assumed contained the same functionality (plus more) as the 'Edit' dialog. It looks like i was wrong. If i setup the Lookup through the Edit page, I can specify the Pass Through columns (which it doesn't look like you can do from inside the Advanced Edit box). Then once i have finished the basic edit i can go in and perform any additional advanced editings.
I suppose it kind of makes sense - my intial attempts at setting Pass Throughs must have been flawed in some other way :)
Hope this helps someone else!
Andrew :)

Although primarily about Master Data Management (MDM) it also covers some of the interesting Fuzzy techniques that can be used with SSIS.
