Prepare alerts for any Odoo document type: sale orders, opportunities, contacts, pickings, so, any existing in your database. There might be an unlimited number of warnings for a record.

Choose which documents of this type should have alerts using the dynamic domain constructor.
You can apply restrictions by any storable field. For example, make announcements only for quotations (not sale orders), warn of invoices with total between 500 and 1000, pay attention only for suppliers (not customers), and so on.

Alerts are located above a form view to always meet the eye of any user who opens this document. Such warnings are updated each time a form is reloaded: when you open a record, when you save a document (including any button clicked), when you switch to a next record, etc.
There are 4 types of alert styles: danger (red), warning (yellow), info (blue), and success (green).
Beside text warnings, you may use simple HTML tags like links, underlining, etc.

Display alerts, if you want, only for pre-defined user groups. For instance, show a warning not for all sales people, but only for sales managers. Take into account, however, that any sales manager always has rights of a sales user.
The right to configure alerts belongs to the special user group – ‘Other / Smart Alerts Admin’. You can assign any user to do that job, but make sure he/she has read rights for a target Odoo model.

Alerts might be translated and, then, would be shown on a current user language.
The tool is compatible with multi companies: each branch has an own list of alerts.
