The S/4HANA Licence Conversion Handbook.

Six outcomes from active conversions.

1. How the FUE conversion arithmetic actually works. The seven Named User categories mapped to the four FUE buckets, the conversion multipliers as published, and where SAP applies them differently in practice.
2. Why brownfield carries hidden licensing risk in 73% of conversions. Engine-metric carry-forward errors, industry-solution mismatches, and custom-code RFC traps that surface only after the technical go-live.
3. The bluefield middle path and what it costs. Selective data transition, hybrid licensing positions, and the contractual landmines that distinguish a defensible bluefield from a hidden re-licence event.
4. How industry solutions remap on S/4HANA. Retail, banking, utilities, and oil & gas industry-solution licensing converts on different terms than the underlying ECC stack — and SAP’s opening proposal often gets this wrong.
5. The thirty-six month conversion roadmap. A month-by-month sequencing of measurement, baseline reconciliation, contract negotiation, and go-live, with the three checkpoints where customers most often lose leverage.
6. The eleven clauses that distinguish a safe conversion contract. Co-termination, conversion-credit treatment, shelfware return, audit-rights re-baselining, and seven more clauses that determine whether the next audit cycle is winnable.
