A migration process has been initiated to transfer the existing SAP system (ECC) to SAP S/4HANA for a leading public operator in urban waste collection and management.

Challenge
The customer needed to migrate to the S/4HANA platform and re-engineer its processes while ensuring operational continuity.
Approach
The approach taken was like-for-like, i.e. aimed at maintaining the structure, configurations and developments of the AS-IS system unchanged, while migrating to the new platform. This was a SAP Brownfield migration, an approach that enabled the transition to S/4HANA while preserving the existing system, with operational continuity and without complete re-engineering of processes.

Solution
Digital Ecosystem
The ECC conversion strategy involved using the standard SUM tool, implementing an initial test phase on a sandbox system and then gradually rolling it out across the entire production landscape. During this phase, it was necessary to adopt a ‘double maintenance’ strategy to keep the two landscapes (ECC and S/4HANA) aligned. For the SAP TARI system, a new landscape was built without business data but compliant with the AS-IS system in terms of data structures, customising and specific developments, using standard conversion tools.
