Final answer:
The correct sequence for 'available to promise' is to ensure the item is on the shelf, not committed, determine pricing, and then check the customer's credit limit.
Step-by-step explanation:
The correct sequence of elements leading to an "available to promise" (ATP) is D. item is on shelf, item is not committed to another customer, determine pricing, check customer credit limit. These steps ensure that a company can confidently promise an item to a customer based on current inventory and customer credit standing. First, the business checks if the item is present in the inventory. Secondly, it confirms the item isn't already committed to someone else, ensuring it can be sold. Thirdly, the pricing is determined, which could vary based on factors such as the quantity ordered or customer-specific pricing agreements. Finally, the seller checks the customer's credit limit to be sure they can pay for the order, thus making the item 'available to promise' to the customer.
