Odoo-18.0-20251222/report_context/readme/USAGE.md

To configure this module, you need to:

• Enter Odoo in debug mode.
• To add a specific context to a report, you should go to Settings -> Reports -> Reporting and look for the report you want to edit on the list. You will see that now they contain a new field called Context Value , where you will be able to add all the desired context parameters.
• Go to Settings -> Parameters -> System Parameters. On the system parameters list, look for report.default.context, which is a Python dictionary variable where you can add a context that will be common for all reports.

It can also be added on the developer side using:

<record id="model_name.report_id" model="ir.actions.report">
    <field name="context">YOUR CONTEXT HERE</field>
</record>
