The default and standard process for goods receipt in SAP Extended Warehouse Management (EWM) is initiated by an inbound delivery. This document is created in the SAP S/4HANA core system (e.g., from a purchase order) and is replicated to EWM as an inbound delivery notification, which becomes the EWM inbound delivery. This EWM inbound delivery is the central object for planning and executing all subsequent goods receipt activities, including unloading and putaway. The term "asynchronous" refers to the timing of the goods receipt posting in Inventory Management, which occurs after the physical receipt steps are completed in EWM, but the process itself is still triggered by the inbound delivery.

A. A purchase order or production order: These are source documents that precede the inbound delivery but do not directly trigger the goods receipt process within the EWM system.

B. An expected goods receipt: This is an alternative document used in EWM when an inbound delivery from the S/4HANA core is not available, but it is not the default requirement for the standard process.

D. A warehouse task: A warehouse task is an executable instruction for a stock movement within the warehouse (e.g., putaway) and is created after the goods receipt process has been initiated based on an inbound delivery.

"Goods Receipt Process in Extended Warehouse Management": "The goods receipt process in Extended Warehouse Management (EWM) is based on the inbound delivery document from the ERP system." This establishes the inbound delivery as the foundational document.

2. SAP S/4HANA Help Portal

"Communication from EWM to SAP S/4HANA": In the context of asynchronous goods movements

the documentation explains that EWM sends the goods movement data to the S/4HANA system after processing the inbound delivery. This confirms the inbound delivery is the prerequisite. (Specific section: Goods Movement Communication).

3. SAP S/4HANA Help Portal

"Expected Goods Receipt": "You can use an expected goods receipt if you want to use a document in EWM as the basis for the goods receipt process

but do not have an inbound delivery from the ERP system." This explicitly defines the EGR as an alternative

not the default. (Specific section: Use).
