Case Study: Aareal Bank Group achieves a future-proof ERP platform with SAP S/4HANA

Aareal Bank Preparing for the Future with a Modern ERP Platform

Aareal Bank Group, a leading international real estate specialist, needed to modernize its core IT systems to improve speed, support innovation, and create a future-proof digital infrastructure for its banking operations. Working with SAP, the bank set out to become the first bank in Germany to fully move its core banking systems to a new digital ERP platform, using SAP S/4HANA and related services.

SAP implemented SAP S/4HANA with SAP for Banking and SAP Value Assurance to simplify the IT landscape, validate core processes, and reduce migration risk. The results included deactivating proprietary developments, cutting customized settings by 75%, reducing data volume by 90% from 2.3 TB to 235 GB, removing more than 70,000 accounts from the chart of accounts, and improving performance through shorter batch runtimes and faster reporting.
