SAP Functional Architect - Plan to Produce

Job Summary

The SAP Functional Architect – Plan-to-Produce drives the architecture of manufacturing planning and execution processes within SAP, ensuring that production workflows from demand planning and MRP through shop-floor execution operate with high performance, accuracy, and reliability.

Job Location

- This role will work hybrid out of our office in the Sandy Springs, GA area.

Job Responsibilities

• Strategy, Architecture & Standards

• Own the PTP target state for all plants (MTS, MTO, ETO or Repetitive, as applicable) using standard SAP PP capabilities, document scope, constraints, and variants.
• Enforce Clean Core: standard first, side-by-side only when strictly necessary; prohibit invasive modifications (user exits, Z-tables) that duplicate standard.
• Define reference patterns for PTP (e.g., production order vs. process order usage, repetitive manufacturing fit, Kanban), including triggering, confirmations, and backflush models.
• Establish NFR guardrails (e.g., MRP runtime windows, posting latency, job concurrency) and operability standards (logging, monitoring, error handling) within S/4HANA.

• Master Data Governance (Build-Once, Reuse Everywhere)

• Govern BOMs, Routings, Work Centers, Production Versions.
• Standardize planning parameters (lot sizes, safety stock, planning strategies, lead times, scheduling margins) by product family/plant.
• Define material master rules for PTP-relevant views and ensure alignment with PTC, OTC and RTP.

• Security, Controls & Compliance

• Define role/authorization needs for planners, schedulers, supervisors, and operators; enforce SoD around master data vs. execution.
• Ensure auditability for order changes, confirmations, yield/scrap edits, and routings/BOMs; maintain a complete traceability chain.

• Testing & Quality Assurance

• Define E2E scenario packs: Demand → MRP → Order → GI → Confirmation → GR → QM → FI/CO postings (incl. rework/scrap/returns).
• Provide SIT/UAT scripts for high-volume flows, constraints (finite capacity where used), and edge cases (shortages, substitutions, partials).

• Cutover, Go-Live & Hypercare

• Establish dress rehearsal criteria (mock MRP, pilot orders, stock adjustments) and production validation steps (first-article checks, day-1 throughput).
• Set hypercare KPIs - Drive root-cause and permanent fixes.

• Collaboration with Product Owner

• Prioritize enablers that increase throughput, schedule adherence, and yield; co-own decisions impacting lead times and capacity.

Target Architecture & Blueprint Deliverables

• End-to-end process architecture for the functional domain
• SAP Target State Design covering standard vs. extensions
• Functional Blueprint Document (process flows, variants, decision logs)
• Cross-module architecture with OTC/PTC/RTP integration points
• Integration contracts (API/IDoc mapping, sequencing, error handling)
• Non-Functional Requirements (performance, security, auditability)

WRICEF & Build Design Deliverables

• WRICEF inventory + complexity scoring + dependency mapping
• Approved WRICEF Functional Specifications
• Prototype configurations, demo scripts, and design validation materials

Master Data Deliverables (in collaboration with MDM Team)

• Master data standards (materials/BOMs/Routings/PVs/Work Centers)
• Support to conversion mapping documents (legacy → S/4HANA)
• Cutover data load requirements + mock load execution criteria

Testing Deliverables (in support of QA Team)

• End-to-End (E2E) business scenario catalog
• SIT test scripts with cross-domain flows
• UAT business scenarios, acceptance criteria, and test evidence
• Regression test packs + automation candidates for future releases

Deployment Deliverables

• Cutover plan inputs (sequence, dependencies, freeze windows)
• Functional readiness checklists
• Production validation scripts
• Hypercare playbooks + issue triage protocols
• Business stabilization metrics (defect rate, bounce-backs, rework)

Job Requirements

• Required

• A 4-year degree in Computer Science, Information Systems, Engineering, or equivalent discipline
• At least 10–15 years SAP PP/PTP experience in S/4HANA (MRP, Production Planning, Production Execution, Capacity Planning).
• Integration knowledge across OTC, RTP, PTC, and CPQ for make-to-order or variant-driven production.
• Experience designing solutions for multi-plant operations, alternate resources, capacity leveling, and bottleneck analysis.
• Strong understanding of manufacturing master data governance.
• Experience with high-volume or complex manufacturing flows: MTS, MTO, ETO, repetitive manufacturing.
• Demonstrated capability to optimize process performance through NFR definitions.
• Skilled in reviewing WRICEF objects such as production reports, custom MRP logic, Shop Floor paperwork printing capabilities.
• Experience supporting UAT, regression, cutover, and hypercare in multi-plant deployments.
• Ability to govern clean-core, BTP extension strategy, and integration architecture.
• Executive-ready communication, decision facilitation, and risk articulation.
• Ability to mentor Functional Leads and elevate the CoE's maturity.

• Preferred

• SAP PP certification.
• Background in manufacturing, distribution, or make-to-order environments.
• Exposure to variant configuration or advanced planning engines.
