In the example illustrated below, company A and company B each have a zip code table. Whenever a zip code is viewed, edited, created, or deleted; Microsoft Dynamics AX references the respective zip code table. If a new zip code is needed, it must be added to both company tables.
If a virtual company is setup to contain the zip code table and Company A and Company B are both linked to this virtual company then the zip code tables in company A & B are not used. Instead both companies point to the virtual company table for zip codes. If a new zip code is added in company A, it is being added to the virtual company table and therefore will be available in company B.
The A.O.T. can also be used to view what tables exist in each of the collections
