In an Odoo multi-company environment you can choose to have a Common Product Catalog so that products can be shared across companies.
For shared products (no company selected) the fields for Stock Input and Output accounts (for example) will be displayed correctly for the current company in the user interface (Form View or List View), and if I download data it shows the correct fields.
So how is this stored in the database, and how can you use Automated Actions against these fields?
