Lookup table dimension_key values should be existed in fact table

Hi All,

I have two source tables. One for a Dimension table and another for a Fact Table.

First I need to load Dimension table to target table by  key_genrating transform to generate a unique dimension_key.

After that need to use this dimension key to load the data to Fact table. Dimension_key values should be exist in Fact Table to maintain the relationship.

How to achieve this?

Please advise.

Thanks in advance.
