Data Model with Multiple Companies
In order to deal with potential duplicated IDs, you'll probably need to re-index the Customers, Salesperson, Buyers, and Vendor tables so that it's possible to have, for example, the same customer/buyer/vendor associated with multiple companies. Sales and Purchases should get a new Company ID column each. The other dimension tables could as well, but don't necessarily need active relationships with Company.
This is my basic idea:

Thanks for the quick response on this! I was anticipating the need to re-index my lookup tables due to duplicate values.
I like your suggestion to introduce Company where you did. However, won't this cause an issue where the Company table will be filtering the Inventory table via both Sales and Purchases? I could get around this by deactivating the relationships from Company to Sales/Purchases in the model and then using CROSSFILTER to activate in my measures as necessary. Is this along the lines of what you were suggesting?
