When deciding whether prices from a delivery document are transferred into the subsequent billing document, which SAP configuration object does the system primarily evaluate?

Introduction / Context:
In SAP Sales and Distribution, pricing can be determined at several stages, including sales order and delivery, but the final revenue posting is usually based on the billing document. The system must decide whether to carry forward pricing information from earlier documents such as deliveries into the billing document or to redetermine prices. This behaviour is controlled by copying control, a configuration object that defines how data moves between document types. The question asks specifically which copying control level the system evaluates when deciding on price transfer from delivery to billing.

Given Data / Assumptions:
- A delivery document is followed by a billing document. - Pricing exists in earlier documents and may be reused or redetermined. - Copying control can be configured at both header and item levels. - We assume standard SAP behaviour for delivery to billing copy control.

Concept / Approach:
Copying control between delivery and billing is maintained in configuration and includes settings at both header and item levels. However, the decision about quantity and value transfer, including whether to copy existing prices or redetermine them, is mainly controlled at the item level. At this level, there is a field that indicates how quantities and values are handled during copying. By adjusting these settings, you can enforce redetermination of pricing or use the values from the preceding document. Therefore, we must focus on the item level copying control when answering this question.

Step-by-Step Solution:
Step 1: Recall that copying control is defined between source and target document types, such as delivery and billing. Step 2: Recognise that the header level primarily controls general document relationships, while item level controls detailed behaviour for each line. Step 3: Remember that the quantity and value plus or minus control, which influences price transfer, is part of the item level configuration. Step 4: Evaluate each option to see which one directly refers to item level copying control between delivery and billing. Step 5: Select the item level copying control as the place where the system checks how to handle pricing during document transfer.

Verification / Alternative check:
In a practical example, if a company wants the billing document to always redetermine prices, consultants adjust the item level copying control so that the system does not simply copy values from the delivery. Conversely, if the company wants to freeze prices at delivery, they configure the item level settings to carry forward the values. When testing in a system, changes at header level alone will not affect this price transfer, while adjustments at item level will, confirming that item level copying control is the key configuration point.

Why Other Options Are Wrong:
Option A: The delivery document type identifies the source document but does not itself control whether prices are copied to billing. Option B: The schedule line category affects availability and requirements in the sales order, not the price transfer from delivery to billing. Option C: Header level copying control manages overall document relationships but does not contain the detailed control for quantity and value handling per item.

Common Pitfalls:
A common mistake is to assume that because document types are defined at header level, all behaviour including pricing is controlled there. Another pitfall is overlooking the importance of item level copy control when troubleshooting pricing problems between delivery and billing. To avoid these issues, always remember that detailed behaviour such as quantity and value transfer is configured at item level. When faced with exam questions on this topic, look for references to item level copying control to identify the correct answer.

Final Answer:
The correct answer is Copying control settings at item level between delivery and billing.
