How to configure discount on courses in ecommerce?

Hi everyone. We are using Juniper version. We have setup and configured discovery and ecmmerce services along with LMS and CMS and they are running.
I wanted to know how can I show discounted prices on ecommerce checkout page?
I found about Programs and Program Offers in Open edX and I configured them but still I am unable to fetch discount on checkout page.

Any one know how to configure discounts in Open edX?
