Answer 1

Cette erreur se produit lorsque vous essayez de rechercher ou d'accéder à un ID d'enregistrement qui n'existe pas, je pense que votre problème est peut-être d'ici

order_obj = self.pool.get('ratecard.multiple').browse(cr,uid,ids)[0] 

Vérifiez l'ID que vous passez à la fonction, il probablement doesn n'existe pas dans la base de données, vous pouvez l'imprimer sur la console ou un fichier journal, puis inspecter votre base de données avec psql et le voir existe.
