Need assistance how to override the set_total_advance_paid in AccountsController Class

[Pejay]

Is there anyone knowledge about overriding AccountsController Class or directly override its method. I have tried overriding by subclass through Journal Entry since I have there an issue with validation but None of my configuration works.

Your response will be greatly appreciated. Thank you!

If you want to override a method which is not a whitelisted and not under a class , refere this documentstaion

How can I override method of core doctype which is not class method or whitelisted method?

Recently i found a solution: Suppose we have a function send_mail in email_campaign.py path: apps/erpnext/erpnext/crm/doctype/email_campaign/email_campaign.py there is a method send_mail which is not whitelisted and not under any class [image] Override steps: Create a .py file in your custom app and do changes in send_mail function Goto __ init __.py file add paths like this [image] Now it will override the send_mail function @Rajvi @Aghiles
