we use ZOHO SUBSCRIPTION to record the subscription to our magazines and there are employees that shall have visibility ONLY on the invoices generated/related to subscription.

What happens is that these employees have visibility over the full set of invoices recorded in ZOHO BOOKS (the full company accounting) and this quite wrong/inappropriate.

It is important to set special properties/privileges to limit the visibility of some employees ONLY to the invoice for Subscriptions and not access financial data in BOOKS.
