SAP S/4HANA core
On-premise · RISE Private · Public Edition
The reference S/4HANA system. Customer ERP data and processes. RHP consumes and exposes via released APIs / OData V4.
03 · Architecture
Product, integration and runtime, separated.
RHP separates each plane so the deployment choice depends on the edition, not on the product. The functional core lives in SAP S/4HANA; RHP adds the healthcare domain; BTP ABAP Environment provides the cloud runtime when decoupling is needed.
RHP product core
ABAP · RAP · CDS · OData V4
The healthcare domain built with the latest SAP standards. OData V4 services covering the full clinical lifecycle. Native extensibility through RAP.
BTP ABAP Environment
Steampunk · ABAP Cloud
Cloud-native runtime when the edition requires it (Public Edition) or when the scenario demands decoupling lifecycle and operation. Fiori apps and SAP Build Work Zone.
gCTS + ATC
Versioning · readiness gate
gCTS for versioning and transport traceability; ATC Cloud Readiness as a cloud-compatibility gate bound to the commit. Every change is associated with version, transport and ATC result.
Deployment choice
On-stack or BTP
On-stack for on-premise and RISE Private. BTP ABAP Environment for Public Edition. The same architecture supports both — no rewrite.
