DIGITAL TRANSFORMATION OF SUPPLIER COLLABORATION: A CASE STUDY ON MIGRATING LEGACY SNC SYSTEM TO SAP BTP

Digital transformation is increasingly critical for procurement organizations in asset intensive industries, where supplier responsiveness, logistics accuracy, and operational continuity are essential. This study examines the modernization of a legacy Supplier Network Collaboration (SNC) system within a major oil and gas enterprise through its migration to a unified DigitalSupplier platform. The legacy SNC environment suffered from fragmented workflows, limited mobility, redundant identity management processes, and restricted real time visibility, all of which negatively affected supplier onboarding and the accuracy of Advanced Shipping Notifications (ASNs). Using the SAP Activate methodology, the transformation introduced seven integrated SAP Fiori and SAP UI5 applications synchronized with SAP S/4HANA and supported by centralized master data governance. A 90 day parallel run was conducted to compare the performance of SNC and DigitalSupplier. The results demonstrate significant improvements: supplier onboarding time decreased from five working days to one hour, adoption increased by 40%, support tickets declined by 20%, and ASN errors were reduced by 10%. These findings empirically support the Technology Acceptance Model (TAM) and align with Digital
