Which of the following is NOT a standard procurement process in SAP S/4HANA?

The standard procurement processes in SAP S/4HANA include activities that are directly related to acquiring goods and services. A purchase requisition is an internal request to procure goods or services, which is subsequently converted into a purchase order. A goods receipt is part of the logistics process that involves the acknowledgment of accepted goods into inventory after procurement. A purchase order, on the other hand, is a formal request sent to a vendor to deliver specific quantities of a product or service.

In contrast, a sales order is not part of the procurement process; it pertains to the sales and distribution module of SAP S/4HANA. A sales order is created by a business when it sells products to customers, marking the initiation of a sales transaction rather than a procurement activity. Thus, it does not fit within the standard procurement processes of the SAP S/4HANA system, confirming that this is indeed the correct choice as it does not relate to the procurement workflow of acquiring goods or services.
