SAP S/4HANA Solution Architect - P2P (Accounts Payable)

Job Description

Purpose of the role

Based at METRO Digital India in Pune, the SAP S/4HANA Solution Architect P2P will own the end-to-end solution architecture for Purchase to Pay within LUCA. The role combines deep functional understanding of procurement, accounts payable and invoice-management processes with the technical judgement required to govern integrations, workflows, extensions and implementation decisions. Working with Process Leads, Process Owners, country teams, technology teams and implementation partners, the architect will ensure that SAP AP, SAP MM, SAP Ariba, OpenText Vendor Invoice Management and connected systems operate as one coherent solution.

Your responsibilities

Solution architecture and design

• Own the end-to-end solution architecture for the P2P process stream across SAP S/4HANA Finance, SAP procurement solutions and connected partner systems, ensuring alignment with the LUCA global template and METRO architecture principles.
• Translate business requirements into coherent functional and technical designs covering procurement-to-invoice integration, supplier invoices, accounts payable, payment preparation, purchasing integration, service and maintenance procurement, SAP Ariba and OpenText Vendor Invoice Management.
• Lead and support Fit-to-Standard workshops, identify gaps and determine whether requirements should be addressed through standard functionality, process change, approved extensions, interfaces or workflow design.
• Advise Process Leads and Process Owners on architectural decisions and their implications for business operations, controls, invoice processing, data, integrations and supportability.
• Review and approve end-to-end designs, configuration concepts, functional specifications, workflow designs and integration solutions within the assigned architecture scope.

OpenText VIM and integration governance

• Provide solution-architecture leadership for OpenText Vendor Invoice Management integrated with SAP S/4HANA, including invoice capture and ingestion, validation, business rules, approval workflows, exception handling, posting and status transparency.
• Ensure the VIM solution supports relevant PO-based and non-PO invoice scenarios and is coherently integrated with SAP AP, MM, Ariba and associated document and workflow services.
• Assess VIM enhancements and configuration choices for alignment with business controls, auditability, operational efficiency, clean-core principles and sustainable support.
• Ensure consistent integration across SAP AP, MM, PM, Ariba, OpenText VIM and relevant upstream and downstream partner systems.
• Oversee interfaces, extensions and enhancements, minimising unnecessary deviation from standard solutions and protecting maintainability.
• Identify cross-stream dependencies with Finance, procurement, master data, integration, security, tax, reporting and country rollout teams, and drive them to resolution.

Testing, deployment and stabilisation

• Define architecture-relevant acceptance criteria and support integration, end-to-end, workflow, regression and user-acceptance test preparation for P2P and VIM scenarios.
• Support defect analysis and resolution, including review and approval of solution corrections and required transports within the P2P scope.
• Provide architectural input to supplier and transactional data migration, cutover planning, system-readiness assessment and go-live decisions.
• Support post-go-live stabilisation, analyse invoice-processing bottlenecks and recurring defects, and identify opportunities for process and system optimisation.

• Strong practical experience with OpenText Vendor Invoice Management for SAP Solutions, including invoice processing, workflow, exception handling, integration and deployment in an SAP environment.
• Good knowledge of SAP Ariba integration and procurement processes; knowledge of SAP PM-related procurement scenarios is advantageous.
