Design and implementation of the RF transactions to interface with SAP's WM (Warehouse Management)-module. In 2001, Autover started its new distribution centre in Bastogne. HUM (handling unit management) is a key feature of the WM implementation. Autover has chosen to use Teklogix hardware and middleware software (TEK-Console) for mobile communication with SAP. The standard SAP WM Idoc's are used to confirm, pack, unpack, do cycle counting... In addition to RF program design, active support in Idoc debugging and SAP configuration was part of the charter. The project was concluded with a dedicated WM and RF training and on-the-floor support during implementation
