Issue with AR Receipt Application

Dear Experts,

I have a customer receipt (Unapplied) and now I am applying to Refund and selecting the details in the refund attribute window and then click on Apply and Save. At this time, I am getting an error window which says, "Transaction completed successfully". Refund is not resulting in creation of AP invoice in the name of customer party. My AP and GL Period is in the Open status.

Earlier this was working fine and no changes are made in the system.

Can you guys please guide me how to resolve this issue.

Thanks in advance.
