Quote blocked due to one-time coupon

Problem Description

When a quote is accepted and invoiced immediately, there is an error message stating that the "Coupon ABCD cannot be applied to the line item"

Root Cause

This happens when a one-time coupon is previously added to one of the line items or to the quote

Solution

• The quote should be declined and a new quote should be created with another coupon which is not a one-time coupon.
• Or one-time coupon should be updated to some other value before closing the quote.
• This is marked as expected behaviour by the product and hence there is no alternate solution to resolve this.
