How to Reduce SAP EWM–ASRS Retrieval Failures Before Wave Release

Consider the following scenario: A pallet finishes its move through the automated storage and retrieval system, but SAP Extended Warehouse Management (SAP EWM) never processes the warehouse task confirmation. Nothing looks wrong until an outbound wave releases and picking fails on stock the system was counting on. By then a truck is at the dock and a stranded pallet is holding an exit spur that other pallets need. This post walks through a pre-release validation step that catches the difference earlier: compare the stock SAP EWM expects to use against what the automated storage and retrieval system (ASRS) reports as stored, and hold the wave when a critical field does not agree. It covers how the mismatch forms, what the comparison checks, how an exception cockpit presents the result, and what to settle during design. How Pallets Move Through an Automated Warehouse SAP EWM with SAP S/4HANA and ASRS work together, but they do not store exactly the same information. SAP EWM manages handling units (HUs), stock, warehouse documents, logical locations, and warehouse tasks. The ASRS, often coordinated through a warehouse control system (WCS), tracks where pallets are physically located a...
