Context

Migration of SAP ECC environments to S/4HANA in the public administration sector, reviewing existing custom code to ensure compatibility and optimization in the new environment.

What I built

Analysis and adaptation of custom developments no longer compatible with the simplified S/4HANA data model.
Development of CDS Views to expose and re-model data according to the new paradigm.
Enhancement of standard Fiori applications with targeted extensions.
Performance tuning of the migrated objects.

Outcome

A custom application landscape aligned with S/4HANA — cleaner, more maintainable code ready to leverage HANA's in-memory capabilities.
