I’m working on a custom wizard and need some help defining a domain between two Many2one fields.

Here’s the setup:

class StockMoveRequestReportWizard(models.TransientModel):
    _name = "stock.move.request.report.wizard"
    _description = "Stock Move Request Report Wizard"

    source_store_id = fields.Many2one(
        'res.store',
        string='Source Store',
        default=lambda self: self.env.user.store_ids,
    )
    destination_store_id = fields.Many2one(
        'res.store',
        string='Destination Store',
    )

The res.store model has a company_id field.

What I want to achieve is:

• When a source_store_id is selected, the destination_store_id field should only show stores that belong to a different company than the selected source store.
