Hi,

When creating a new task from the Project dashboard, Odoo automatically passes certain context values — such as sale_line_id — especially if the task is being created from a related Sales Order. If you want to remove the sale_line_id from the context to make the task independent of the sale order, you can override the context in your custom module.

Here’s how you can handle it:

Inherit the Action or Button:

Go to Settings → Technical → Views and locate the action used for creating tasks.

Override the Context:

In your custom module, inherit this action and remove the sale_line_id from its context:

<record id="action_view_task_custom" model="ir.actions.act_window">

<field name="inherit_id" ref="project.action_view_task"/>

<field name="context">{'default_sale_line_id': False}</field>

</record>

Alternative:

You can also override the create method of the task model and simply pop the key:

@api.model

def create(self, vals):

vals.pop('sale_line_id', None)

return super(ProjectTask, self).create(vals)

This ensures that the sale_line_id won’t be linked automatically when creating new tasks from the dashboard.

Hope it helps
