SAP ECC to S/4HANA: The License Cost Impact

Why the ECC to S4HANA conversion changes the license cost shape

The ECC to S/4HANA conversion changes the license cost shape because the named user model under ECC converts into the FUE model under S/4HANA, the document creation triggers the digital access metric, and the ECC engine portfolio consolidates into the S/4HANA core engines. The customer that approaches the conversion without the cost model exposes the program to the run rate that exceeds the planned outcome. The customer that builds the conversion cost model on the named user reclassification, the digital access reset, and the engine consolidation lands the program within the modelled run rate. Reference the S4HANA licensing pillar, the license audit complete guide, and the S4HANA expertise.

Named user reclassification and the FUE conversion mechanism

The named user reclassification under S/4HANA replaces the ECC professional, limited professional, employee self service, and platform user categories with the Full Use Equivalent (FUE) model. Every S/4HANA user maps to the FUE on a defined ratio. The professional user maps at one to one. The functional user maps at one to five. The productivity user maps at one to thirty. The developer user maps to a dedicated category. The customer that runs the FUE reclassification on the ECC user base before the conversion produces the FUE count that the S/4HANA contract requires. Reference the named user types, the professional vs limited, and the license reclassification.

Digital access metric and the document count exposure

The digital access metric under S/4HANA counts the documents that the third party systems create in the S/4HANA core. The ECC contract did not include the digital access metric for most customers. The conversion to S/4HANA exposes the document count to the metric for the first time. The customer that maps the third party document flow before the conversion sizes the digital access entitlement on the validated count rather than the SAP measurement program output. The digital access exposure is the largest single cost item on most ECC to S/4HANA conversions. Reference the indirect access explained, the digital access pricing, and the indirect access detection.

Customer programs that model the ECC to S4HANA license cost with the named user reclassification, the digital access reset, and the engine consolidation in one financial view land the conversion within approximately 88 percent of the modelled run rate.

Engine consolidation, retirement, and the run cost reduction

The engine consolidation under S/4HANA retires several ECC engines into the S/4HANA core. The HR engine consolidates with the S/4HANA HR module on the named user count rather than the headcount engine. The CRM engine consolidates with the S/4HANA customer module. The SCM engine consolidates with the S/4HANA logistics module. The engine retirement reduces the engine entitlement that the customer carries on the S/4HANA contract. The customer that maps the engine retirement against the ECC entitlement claim returns the engine drop as a run cost reduction in the S/4HANA business case. Reference the engine licenses analysis, the HANA runtime analysis, and the license harvesting reclaim.

Negotiation posture and the conversion contract framework

The negotiation posture and the conversion contract framework cover the conversion credit, the FUE pricing schedule, the digital access initial allocation, the engine retirement credit, the contract term, and the renewal posture. The conversion credit recognises the residual ECC entitlement on the new contract. The FUE pricing schedule defines the run rate. The digital access initial allocation defines the document entitlement on the new contract. The engine retirement credit returns the ECC engine entitlement drop. The contract term defines the commitment window. The renewal posture defines the position for the next negotiation cycle. Reference the compliance framework pillar (cross cluster), the security audit pillar (cross cluster), and the renewal negotiation expertise.
