Hi Ranoa,

You can specify this condition in the form view.For that you will have to check if the company_id field value of the record equals to the company which you have to hide that field.Create a new field named hide_company_id and store the id of the company “company B”.(the company id from which you want to hide that field, basically the value will be an integer the actual id value).Then add this condition in the field definition.

field name="your_field" attrs="{'invisible': [(company_id, '=', 'hide_company_id')]}"/>

Regards
