Facxt Table Example

I need an example that shows how to uses multiple lookups to populate a fact table. The flow goes lilke this...

1. Read a staging table source that has source keys

2. for each source key, perform a lookup on the dimension table and return the surrogate key

3. Insert rows into the fact table with the surrogate keys

This is a standard approach that I've done many times in other ETL tools. However, I can't find any examples on how to get it to work. I have tried stringing the lookups together sequentially and using a multicast to peform the lookups in parallel. Neither approach would work. I could not find any examples on the web or in the SQL2005 samples.

Thanks,

Take a look at the samples you can download here:

This book is what I'd categorize as a "must have" if you're going to be spending much time with the MS BI stack.
