Inherited means that users added to this application group are automatically added to the following ones. In the example below, users who have access to the group Administrator of Sales also have access to Website/Restricted Editor and Sales/User: All Documents.
Remember to always test the settings being changed in order to ensure that they are being applied to the needed and right users.
The Menus tab is where you define which menus (models) the user can have access to.
Access Rights rules are the first level of rights. The field is composed of the object name, which is the technical name given to a model. For each model, enable the following options as appropriate:
Read: the values of that object can be only seen by the user.
Write: the values of that object can be edited by the user.
Create: values for that object can be created by the user.
Delete: the values of that object can be deleted by the user.
Making changes in access rights can have a big impact on the database. For this reason, we recommend you to contact your Odoo Business Analyst or our Support Team, unless you have knowledge about Domains in Odoo.
