Hi,

I added a field called invoice_id on stock.picking. I want to add some domain to show only sale invoices or purchase invoices depending on picking_type. Any ideas?

I have this:

invoice_id = fields.Many2one('account.move','Invoice', domain=lambda self: [('type', 'in', ['in_invoice','in_refund'] if self.picking_type_id.id == 1 else ['out_invoice','out_refund'])])
