Which of the following options ensures no changes are made to SAP-delivered objects when standard sales processing logic is to be changed?

The correct option ensures that changes made to standard sales processing logic do not affect SAP-delivered objects, which is a crucial aspect of maintaining system integrity and supportability. Enhancement Points are predefined locations in SAP code where customers can implement their custom logic without modifying the original SAP code. This means that when SAP provides updates or patches, the customized enhancements remain intact and operational since they are separate from the standard objects.

Using Enhancement Points allows companies to adapt standard functionality to meet their unique business requirements while preserving the core standard processes. This approach not only adheres to best practices but also helps in maintaining a clear upgrade path for SAP applications, minimizing potential disruptions during system updates.

In contrast, Customer Exits and Business Transaction Events (BTE) also provide ways to enhance functionality, but they might involve more direct interaction with the existing code or configurations that could be at risk during standard updates. Business Process Re-engineering focuses on reevaluating and redesigning processes, which doesn't directly speak to the technical preservation of standard objects in the same way the Enhancement Point does.
