Hello,
From CRM module, you have an option to create new Quotation from a Button, and if I check as developer, I see that is pointting to an action id=429. If I search "New Quotation" string I see a button that is calling "sale_action_quotations_new" that is inside a xml calling Quotation sales orders, but I'd like before calling this button, add some checks but I don't know how to access the py code function associate and I don't know how to extend it. Can you help me?
Thanks
This is the code:
