Sharing Data and report on a Multi-tenant architecture

[BigRider]

Hi Experts,

I have an installation in a multi-tenant architecture for a holding/group fo companies with 06 tenants and I have a report created to attend all of companies.

However, only each company can see its data when they are logged into its tenant. 

The questions are:

Must I deploy this report on each tenant filtering and generating subsets of data? 

Data of each company must be copied in each tenant or can I share a centralized report applying row-level security for access the data?

Is there any documentation of access data and content works in a multi-tenant architecture ?

Thanks in Advance,

Regards,

Multi-tenancy prevents tenants from seeing each others data by design, so you would not be able to share data/content between tenants.
