At present there is no option available for B2B customer to perform a return from the D365 commerce web shop. For performing a return the customer need to reach out to then seller on email or on a call and then a return order is created on the D365 F&O. To avoid this cumbersome process then customer wants to perform a return on the B2B site itself. Also they want to see the credit note information under the My Account section for the returns they have performed from the B2B site. Looking forward to have it on the next release to make the website more user friendly for customers.
