Abstract

Warehouse task proliferation — the uncontrolled growth of discrete Warehouse Tasks (WTs) generated per replenishment cycle — is a documented inefficiency in high-SKU distribution environments operating SAP Extended Warehouse Management (EWM). Standard EWM replenishment triggers generate one WT per Storage Bin per replenishment event, producing hundreds of redundant pick-and-put tasks during peak periods when multiple ODOs request the same source material within a single planning window. This article presents a configurable queue-based consolidation architecture implemented through a custom BAdI enhancement of the POSC replenishment framework. The architecture intercepts WT generation at the process step level (OB31/OB32 AES sequence), evaluates pending replenishment demand across the active planning horizon, and consolidates multiple replenishment requests into a single optimised WT where source bin, destination zone, and material type are compatible. A custom table (ZCARTDET) externalises consolidation parameters, enabling warehouse managers to adjust consolidation thresholds without ABAP development access. Deployed at a large US healthcare distributor across Stryker and Johnson & Johnson distribution sites, the architecture reduced active WT count during peak hours by 62%, decreased average replenishment cycle time by 28 minutes, and delivered an annual operational saving of USD 350,000 (Author's primary implementation data, 2023). The contribution is a documented design pattern — BAdI-driven queue consolidation within EWM POSC — supported by primary enterprise deployment evidence.
