In a decentralized SAP S/4HANA Extended Warehouse Management (EWM) environment, the system uses pairs of documents for communication and processing. These typically consist of a request document and an execution document. While the initial request document from the S/4HANA core system (like an Outbound Delivery Request) can often be skipped, the core EWM documents for execution and final confirmation are mandatory.

The Outbound Delivery Order (ODO) is the primary execution document within EWM, used to manage all warehouse activities like picking and packing. The Outbound Delivery (OD) is created upon posting the goods issue in EWM and is essential for communicating the final stock removal back to the S/4HANA core system. Both documents are indispensable for completing the outbound process and ensuring stock consistency between the systems.

B. A production material request and a stock transfer: A Production Material Request (PMR) and a stock transfer are separate business processes and not a mandatory, linked pair of document categories in the same way as delivery documents.

C. A posting change request and a posting change: The Posting Change Request (PCR) is the notification from the S/4HANA core. This request can be skipped, and a posting change can be initiated directly in EWM.

D. An outbound delivery request and an outbound delivery order: The Outbound Delivery Request (ODR) is the initial request from the S/4HANA core. This document can be skipped, as an Outbound Delivery Order can be created directly in EWM.
