Case Study: WWZ (Swiss utility & telecom) achieves 9X faster SAP data extraction and rapid self‑service portal rollout with Boomi aXis for SAP

WWZ Innovates Its Cable-Internet Services by Modernizing Its SAP Data Ecosystem

WWZ AG, a Swiss utility and telecom provider serving roughly 72,000 utility customers and 60,000 cable‑internet subscribers, needed to bundle services and launch a customer self‑service portal. The IT team faced a complex challenge: continuously extracting large volumes of SAP ERP data to feed multiple third‑party OSS/BSS applications while planning a migration from SAP R/3 to S/4HANA; existing SAP PI integrations would have been costly and required rebuilding about 32 interfaces.

WWZ implemented Boomi aXis for SAP, creating a replica of its SAP R/3 database to connect SAP and third‑party systems to the new portal without impacting production. The solution sped SAP data extraction by 9X, dramatically reduced interface build time, enabled the launch of new subscription services for 60,000 customers, and established a reusable data layer to support insights, future S/4HANA cutover, and further innovation.
