I have a fact table that has 17 keys. Normally I have been designating the primary key as all of my dimensional keys. MS SQL server 2008 has a limitation of 16 columns in a primary key or unique constraint. Are there any work arounds?

I downloaded Microsoft’s project real. They do not include all keys in the pk. There are 2 scenarios. If all the keys actually are unique per the business rules then that is the pk. 2- If there are more keys on the table than what makes it unique per the busines rules, then a clustered index is used on the unique keys and the table doesn’t have a primary key.
