sap-s4-migration

What problem does it solve?

Migration to SAP S/4HANA is complex and high-risk, involving choice of approach, interpretation of readiness check simplification items, mass Business Partner conversion, extensive custom code remediation, data migration and cutover validation; this Skill consolidates best practices, checks, and stepwise remediation guidance to reduce go-live risk and rework.

Core Features & Use Cases

• Approach decision tree: clear guidance for brownfield (system conversion), greenfield (new implementation), and selective data transition (bluefield) choices.
• Readiness Check & Simplification Item analysis: prioritized interpretation of critical simplification items by module with recommended resolutions and effort estimates.
• Business Partner (CVI) migration: pre-checks, configuration, mass conversion steps, common errors and fixes, and reconciliation guidance.
• Custom code remediation (ATC): common ATC findings, replacement patterns (ACDOCA/MATDOC/CDS), triage process and remediation priorities.
• Cutover & post-migration validation: phased timeline, dry-run recommendations, cutover day checklist and hypercare validations for FI/MM/SD/ABAP.
• Usage example: run readiness check outputs and ATC reports, then apply this Skill to produce a prioritized remediation backlog, BP migration plan and cutover checklist.

Quick Start

Analyze my Readiness Check and ATC results and produce a migration approach with prioritized simplification item fixes, a Business Partner migration plan, an ATC remediation triage, and a cutover validation checklist.
