Executive Summary
Asitek successfully implemented a real-time integration between HighJump WMS and SAP ERP for a major retail client. This transformation enabled seamless data flow across 5 regional distribution centers and 300+ retail stores, leading to higher operational efficiency, better inventory accuracy, and improved customer service levels.
Client Overview
Industry: Retail (Apparel, Home Goods, FMCG)
Scope: 5 Distribution Centers (DCs), 300+ Retail Stores
ERP System: SAP ECC (transitioning to SAP S/4HANA)
WMS: HighJump (Körber)
Objective: Optimize end-to-end warehouse operations through real-time SAP-WMS integration
Pain Points Identified
Inventory discrepancies over 4% due to delayed/manual updates
Slow and error-prone returns management (avg. >48 hours)
4–6 hour delay in data sync between WMS and SAP
Inaccurate order statuses impacted customer satisfaction
Labor-intensive picking and shipping workflows increased cost per order
Our Integration Strategy
Asitek designed a hybrid integration model using SAP PI/PO to enable real-time communication between SAP and HighJump.
Approach included:
Mapping SAP IDocs to HighJump-compatible XML/JSON
Developing custom REST APIs and BAPIs
Implementing retry, logging, and error recovery mechanisms
Building real-time monitoring and audit dashboards
Core Integration Points
Purchase Orders (SAP -> WMS): IDoc ORDERS05
Goods Receipt (WMS -> SAP): IDoc MBGMCR
Sales Orders (SAP -> WMS): IDoc/BAPI integration
Shipment Confirmation (WMS -> SAP): IDoc DESADV
Inventory Adjustments (WMS -> SAP): Custom BAPI
Returns (Bi-Directional): Custom REST APIs and IDocs
Master Data Sync (SAP -> WMS): Batch process using IDoc MATMAS/LOCMAS
Warehouse Execution Flows

SAP SD creates Sales Order and triggers IDoc to WMS
HighJump allocates stock and sends RF-based pick instructions
Once packed and scanned, WMS sends back shipment confirmation

2. Return Management:
Return initiated at POS or via SAP
WMS verifies physical item and inspection process
Return confirmation sent to SAP instantly
3. Inventory Control:
RF-enabled cycle counting
Discrepancy reports automatically posted to SAP
