Main company with virtual companies

Hello.I defined 1 company with 4 virtual companies.

I succeeded to share tables between all the companies

i don’t know how to set up that the company i created (which is not virtual) would be the main company…help [:(].

In each virtual company (= subsidiary) I have created employees. Now i want to see the employee that exists in each company but don’t know how and I also don’t know which report to use in order to see a loaned item for different employees at the subsidiaries.

Can a Biz Talk Server help me in this case? What is its purpose?

I want to add that building an organizational structure with main company and subsidiaries is a very problematic issue , does anyone run into such a complex thing?

I’ll appreciate if someone would enlihgt this for me…

Thanks in advanced.Roni
