SAP Contract C2C
Job title: SAP BW/4HANA Technical Architect – Conversion / Brownfield
Work Location: Juno Beach, FL – Hybrid
Minimum years of experience: 15+ Years
Key Responsibilities
Architecture & Design
Own and sign off the target BW/4HANA data architecture, including ADSO and CompositeProvider design, LSA++ layer strategy, HANA pushdown approach, and data tiering (hot / warm / cold).
Define the conversion approach (Remote Conversion — Brown Field) and govern its execution across Sandbox, Development, QA and Production environments.
Lead the object-classification exercise for all 9,162 BW objects, confirming each as convertible, adjustment-required or nonconvertible, and define the remediation path.
Govern scope rationalisation: drive the reduction of ~1,512 BEx queries to the agreed ~338–350 target, retiring ADHOC (Y*) content and year-based structures with business justification.
Approve architecture design documents, data model blueprints, integration architecture and security framework before development begins.
Conversion & Remediation
Direct the multi-step Sandbox → Development → QA → Production remote conversion sequence, including SUM execution, BW/4HANA Starter Add-on and RFC connectivity setup.
Provide hands-on technical leadership for remediation of the 3,113 nonconvertible + 1,112 adjustment-required objects, including unsupported transformations, InfoPackages, APD-based processes and custom ABAP.
Review and approve all AMDP / SQLScript rewrites and HANA pushdown implementations by the offshore team.
Ensure reporting-layer readiness: BEx query conversion and rework, AFO workbook re-pointing, Power BI and BusinessObjects re-connection, and security role migration (~30–35 roles).
Oversee compatibility of all inbound integrations (SAP S/4HANA, SuccessFactors, ServiceNow, Fieldglass, flat files) and outbound feeds (Finance BW, Open Hub destinations) in the parallel BW/4HANA environment before cutover.
Custom Objects & Integrations
Lead the technical approach for custom Z/Y tables, custom ABAP programs, SAP CPI iFlows and web services — classifying each as retain / re-point / redesign / retire.
Ensure code-inspector and ATC scans are executed and all HANA-incompatible statements remediated before system conversion.
Sign off on SPAU/SPDD completion in Development, and validate that break-fix transport retrofits into BW/4HANA DEV remain aligned with the parallel legacy landscape.
Testing, Cutover & Go-Live
Drive the overall testing strategy: Unit Testing, SIT, Performance Benchmarking, Full Mock Migration, Dress Rehearsal and UAT.
Oversee multi-level automated data reconciliation (record count, aggregates, key figures) at every mock cycle and at production cutover, using the Report Validator accelerator.
Define and execute the Soft Freeze and Hard Freeze governance framework in the lead-up to production cutover.
Lead the production cutover and manage the ~30-hour cutover window across Basis, BW, Infrastructure and Business teams; serve as the on-site decision-maker for go / no-go and rollback.
Provide Hypercare support during the mandatory 4-week post-go-live period, monitoring process chains, integrations and data loads.
Client Engagement & Governance
Act as the primary Infosys technical interface with BW Lead, Basis Team Lead, Security and Infrastructure teams on a daily basis.
Represent Infosys in Weekly Project Status Reviews and contribute architectural input to monthly Steering Committee and Executive Governance Reviews.
Maintain the RAID log for all technical risks, assumptions, issues and dependencies; escalate architectural blockers within 24 hours per the programme’s escalation SLAs.
Manage the Change Request process for technical scope changes, completing impact assessment across schedule, cost and risk before approval.
Conduct knowledge transfer sessions and produce technical specification documentation for newly developed models, ensuring support team can sustain the BW/4HANA landscape post-programme.
