It’s a known limitation in Odoo 10 that the financial report hierarchy isn’t company-specific by default. Since the account.financial.report model doesn’t include a company_id field, any modification to the hierarchy impacts all companies. The practical solution is to develop a custom module that extends this model with a company_id and adjust the financial report views so each company maintains an independent structure.

In one setup, a team handled this by creating separate financial report records for each company and applying access rules based on user permissions. This ensured each company only viewed its relevant financial data while preserving overall system integrity. For organizations managing multiple entities or looking to streamline reporting workflows, integrating professional financial structure planning can make a big difference.
