Final answer:
When a customer declines a back order, the process ends and the order is voided, indicating the transaction will not proceed and no future delivery will occur.
Step-by-step explanation:
If a customer refuses to accept a back order, then the correct response is that the sales event is terminated and the sales order is cancelled. This means the transaction in which the customer was supposed to receive the goods at a later date (back order) will not proceed any further. Instead, the order that was created will be annulled, signifying that there will be no expectation of delivery in the future, and the business should adjust its records to reflect this change.
When a customer refuses to accept a back order, it means they do not want to wait for the out-of-stock item to be restocked and delivered. In this case, it is common practice for the sales event to be terminated, as the customer has declined the offer. Additionally, the sales order is cancelled, as there is no longer a need to fulfill the order.
