Hi Lisa,
There are certain rules to these columns. You would typically have one _key
column in the main and additional _key column for each submain. Dimensions
should have one _key column, identifying which main table they belong to.
Can you give us an idea why do you need more 'key' columns so maybe we can
explain better?
