Hello everyone, i have a problem here. so i created a new boolean field in stock warehouse 

sync_hitoko = fields.Boolean(string='Sync Hitoko',help='Check if you want to sync stock in this warehouse to be sent to hitoko', )

sync_warehouse = self.env['stock.warehouse'].search(['sync_hitoko', '=', True])
