Five-phase SAP S/4HANA implementation for water utilities integrates WEBCON BPS workflow, HADRONE PPM project management, PROPHIX budgeting, INTERGRAPH GIS mapping, and custom mobile apps. Phase 1 (Procure to Pay) flows from A1 through A3 with bidirectional SAP integration. Phase 2 (Order to Cash) manages dual-channel sales via B1-B3 sequence connecting billing systems. Phase 3 (Acquire to Retire) orchestrates capital asset lifecycle C1-C4 with GIS and PPM touchpoints. Phase 4 (Maintenance and Field Service) deploys mobile-first workflows D1-D3 for field crews. Phase 5 (Record to Report) closes financial planning loop E1-E3 via PROPHIX and SAP BTP Integration. This architecture demonstrates end-to-end utility operations modernization on SAP S/4HANA, critical for water companies migrating from legacy ERP systems.
