I have been asked to add a field named Payment Amount in  Accounting App > Customers > Invoice list view, where it has to display the amount when the payment was made. 

1. Created a many to one relation field to make relation with account.payment model

2. Created a related field and related it with account.payment.amount and saved it

I went and refreshed the view and there was no data displayed. How to do it in the right way?
