Rick Markham

SAP S/4HANA Data Migration Leader  |  Architect  |  Practitioner
20+ years leading SAP data migration on major S/4HANA implementations — greenfield and brownfield, on-premise and RISE/cloud. Equally effective as the hands-on architect driving extraction, transformation, and load logic, and as the program lead accountable for mock cycles, cutover planning, and go-live execution. Delivered successful go-lives at CHS, Phillips 66, Coca-Cola, Lockheed Martin, and others across Oil & Gas, Manufacturing, Consumer Products, Life Sciences, Aerospace, and Banking.

What distinguishes this experience is deep functional process knowledge across the end-to-end value streams that S/4HANA RISE transformations are built around: Record-to-Report (R2R), Order-to-Cash (OTC), Source-to-Pay (S2P), Supply Chain & Manufacturing, Hydrocarbon Value Chain / Commodity Trading & Risk Management (HVC/CTRM), and Enterprise Asset Management (EAM). That process depth shapes every migration decision — from object scoping and data migration workshops through cleansing logic and load sequencing.

Migration Architecture

50–70 conversion objects per engagement. End-to-end program design across the full 6-phase lifecycle: scoping, staging, profiling, mapping, DQ, and gold output.

S/4HANA Process Depth

R2R, OTC, S2P, Supply Chain, EAM, HVC/CTRM. Migration designs built around how data flows through the target S/4 processes — not just technically loaded.

AI-Augmented Delivery

Structured use of AI for SQL generation, DQ rule authoring, runbook production, and mapping acceleration. Faster delivery without cutting corners.

Data migration succeeds when the people running it understand both the business and the technology deeply enough to make the right calls under pressure. Tools matter. Methodology matters more. Experienced judgment matters most.

I design migration programs that can be defended in every detail — object scope decisions, cleansing rules, mock cycle results, cutover timing. That discipline is what keeps S/4HANA go-lives on schedule.

20+ Years of SAP Data Migration Experience

20+ years leading SAP data migration on major S/4HANA implementations across greenfield and brownfield programs, on-premise and RISE/cloud. Equally effective as the hands-on architect and as the program lead accountable for mock cycles, cutover, and go-live. Certified in Syniti ADMM and SAP Data Services. Delivered go-lives at CHS, Phillips 66, Coca-Cola, Lockheed Martin, and others across Oil & Gas, Manufacturing, Consumer Products, Life Sciences, Aerospace, and Banking.

Deep functional process knowledge across R2R, OTC, S2P, Supply Chain & Manufacturing, HVC/CTRM, and EAM — the value streams that S/4HANA RISE transformations are built around. Process depth shapes every migration design decision, from object scoping and workshop facilitation through cleansing logic and load sequencing, ensuring data arrives business-ready rather than just technically loaded.
