Abstract : Industrial maintenance facilities managing large non-stock material portfolios face a persistent architectural gap: standard Extended Warehouse Management (EWM) cross-docking does not natively support cost-object allocation -- the direct linkage of inbound materials to Plant Maintenance Orders, Network Orders, Work Breakdown Structure (WBS) Elements, and Cost Centers at the point of goods receipt. This article presents a mobile-integrated cross-docking architecture that resolves this gap through a nine-variant process model executed via Radio Frequency (RF) handheld technology. A custom process code, a Business Add-In (BADI) for extended table population, and RF-driven warehouse task execution form the three integrated layers of the solution. The architecture eliminates intermediate storage for non-stock materials, compresses order cycle time, and establishes real-time financial accountability across maintenance and project logistics -- contributing to operational agility and to the broader digital transformation of industrial supply chain and asset-management ecosystems.
