Implementation of a shared Core chart of accounts under SAP S/4 HANA

A listed group with operations in several countries decided to deploy a single SAP S/4HANA platform to unify its financial practices. One of the objectives was to homogenize local accounting rules and converge them with the standards and principles defined by the Group, guaranteeing consistency between countries. The creation of a "core" chart of accounts shared by all entities was a major lever in ensuring the reliability of financial data.

The approach adopted consisted in classifying the existing accounts of the existing system and the target system in each aggregate defined by the Group, and then carrying out a rigorous mapping with the local accounts. This step was completed by systematic checks to secure the correspondences. To industrialize the roll-out, a roll-out KIT was designed, bringing together methodology, models and best practices, enabling the process to be efficiently repeated in each subsidiary. Last but not least, an appropriate governance structure was put in place, involving local and central teams, to ensure buy-in and sustainability.
