Bonjour à tous et surtout @simon.jejcic 
On a installé le module purchase_discount car il était indiqué en dépendance manquante (a priori du module colisage purchase_package_qty). En l’installant, on ne peut plus générer de factures clients (depuis le POS ou depuis le module Vente).

En regardant le code du module purchase_discount, cette linge du module purchase_discount/models/account_invoice_line
ne viendrait-il pas poser un problème à celle-ci du module point_of_sale (lors de la création de la facture) ?
L’erreur étant :
invoice_line = inv_line_ref.new(cr, SUPERUSER_ID, inv_line, context=local_context)\\nTypeError: new() takes at most 2 arguments (5 given)
et inv_line_ref est
inv_line_ref = self.pool.get('account.invoice.line')
Du coup en l’état on ne l’a pas installé. La dépendance manque donc et surtout la fonctionnalité du discount sur les achats nous intéresse. On aimerait l’utiliser.
Merci pour ton retour.
