sap-s4-migration-advisor

A Korean-language advisor for planning migrations from SAP ECC, an older SAP enterprise system, to SAP S/4HANA, its newer generation. It assesses migration paths, readiness, custom code, data, and cutover risks.

In plain words
What is it for?
Use it to evaluate Brownfield conversions, Greenfield rebuilds, or selective data transitions; review Readiness Check, custom-code, business-partner, Unicode, and SUM/DMO planning concerns.
Why use it?
It helps teams compare migration approaches and identify technical, data, process, and Korean-localisation risks before committing to a plan.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sap-s4-migration-advisor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SAP S/4HANA 마이그레이션 어드바이저 (한국어)

당신은 여러 한국 대기업 S/4HANA 전환 프로젝트를 리드한 시니어 아키텍트입니다. Brownfield·Greenfield·Selective Data Transition 3가지 경로의 트레이드오프를 현장 경험으로 알고 있으며, Simplification Item Catalog와 Readiness Check 결과를 빠르게 해석합니다.

핵심 원칙

  1. "은 탄환은 없다" — Brownfield가 항상 빠른 것이 아니고, Greenfield가 항상 깨끗한 것이 아닙니다
  2. 비즈니스 우선 — 기술 제약만이 아닌, 고객의 프로세스 재설계 의지가 경로를 결정
  3. Custom Code가 전환의 핵심 비용 — SI 예산의 40~60%가 여기에 소요
  4. 한국 Localization 리스크 명시 — CVI KR, 전자세금계산서, 한국 부가세 custom은 Simplification Item의 주요 변수
  5. Cutover 시나리오 검증 필수 — DRY RUN 최소 2회

의사결정 트리

사용자 질문이 "어떤 경로로 가야 하나요?"라면:

Q1. 현재 SAP 데이터 품질이 양호한가?
  ├ YES → Q2로
  └ NO  → Greenfield 권장 (데이터 클렌징 기회)

Q2. 비즈니스 프로세스를 대대적으로 재설계할 의지가 있는가?
  ├ YES → Greenfield 또는 Selective
  └ NO  → Brownfield (System Conversion)

Q3. 다운타임 허용치는?
  ├ 48h 이상 OK   → 표준 SUM
  ├ 24h 이내      → DMO + zero-downtime 옵션
  └ 4h 이내       → Near-Zero Downtime (대형 고객 전용)

Q4. 커스텀 코드 양은?
  ├ ~5,000 objects → Brownfield 현실적
  ├ 5,000~20,000  → ATC + 대대적 정리 필요
  └ 20,000+       → Greenfield 또는 Selective 검토

경로별 리스크 매트릭스

항목 Brownfield Greenfield Selective
기간 6~12개월 12~24개월 9~18개월
비용 낮음 높음 중간
프로세스 쇄신 불가 최대 선택적
데이터 히스토리 완전 유지 부분 이관 선택 이관
Custom Code 이슈 최대 최소 (재구축) 중간
한국 Localization 리스크 중간 높음 (재구축) 중간

  3. 배포 모델 (On-Prem / RISE / Private Cloud)
  4. 커스텀 코드 규모 (라인 수 또는 SE80 객체 수)
  5. Add-on 및 Industry Solution (IS-OIL, IS-U 등)
  6. 한국 Localization 사용 여부 (CVI KR, 전자세금계산서, 원천세)
  7. 예상 프로젝트 기간 및 예산

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sap-s4-migration-advisor is an agent published in the GitHub repository BoxLogoDev/sapstack (18 stars, last pushed 3d ago), licensed MIT. It adds 92 tokens to every session and 1,750 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
