The pilot conversion of the ECC production system copy (an approximately 3.2 TB database size) was performed in less than four months, including interruptions and delays associated with the resolution of more than 50 critical errors detected during the process.
For the conversion, around 400 customizations (enhancements, conversions, workflows, reports, and forms) were analyzed. These exposed possible errors and warning across the associated 33,000 plus code objects. Active Business Functions and Add-Ons were also analyzed for compatibility.
While the pilot environment did not include any external applications integrated with SAP, the Readiness Check report provided a compatibility analysis for the SAP Business Warehouse Extractors showing the impact the S/4HANA conversion would have. The converted S/4HANA system was integrated with upgraded EWM 9.5 and SAP PO 7.5 systems.
One unexpected result of the pilot project was the extent of issues with the master data that was exposed. Zuellig Pharma had not anticipated this and it showed the need to remediate master data, including the Customer / Vendor Integration with both master data combined into the Business Partner master in S/4HANA.
Overall, the pilot conversion provided Zuellig Pharma with invaluable insight into the preparation activities required ahead of the actual conversion to S/4HANA. This included a master data harmonization project triggered by data quality findings and opportunities identified to archive redundant data.
SoftwareONE provided the know-how for a S/4HANA conversion project and the approach for the pilot. This allowed the S/4HANA conversion to be completed in a short time and with minimal resources (people, infrastructure and cost) required from Zuellig Pharma.
The S/4HANA pilot also enabled a change management program to initiate and drive adoption of the new solution by showcasing the improved business processes and functionalities of the S/4HANA solution. The optimized User Interface using SAP Fiori was demonstrated as part of selected scenarios tested to illustrate the benefits of increased productivity and flexibility, focusing on mobile workers.
