  • Oversee functional aspects of integrations across SAP and non‑SAP systems (CPI, APIs, banking, tax engines).
  • Support design of analytics, KPIs, group reporting, and compliance‑related reporting structures.
• Stakeholder Leadership & Business Advisory
  • Act as the trusted functional advisor to Finance leadership, GPOs, and business SMEs.
  • Facilitate solution design workshops, capability assessments, and process maturity discussions.
  • Provide clarity on SAP Finance roadmap, dependencies, and functional implications of design choices.
• Quality Assurance & Delivery Governance
