Neptune Integration Hub for SAP S/4HANA Cloud Public Edition 1.0.0 release notes

October 16, 2026

This is the first release of Neptune Integration Hub for SAP S/4HANA Cloud Public Edition. Neptune Integration Hub for SAP is now available as an ABAP Cloud add-on certified by SAP for SAP S/4HANA Cloud Public Edition. It lets developers expose ABAP logic as REST APIs that are designed in Neptune DXP - Open Edition and executed in the SAP tenant.

The add-on is the fourth flavor of Neptune Integration Hub for SAP, next to the Standard, Cloud, and Combined flavors for on-premise and private cloud systems. It is versioned separately from the Neptune Integration Hub for SAP framework Changes to the Hub API Designer in Neptune DXP - Open Edition are listed in the Neptune DXP - Open Edition release notes.

The add-on is licensed through Neptune DXP - Open Edition. To use it, you need a license for Neptune DXP - Open Edition that covers Neptune Integration Hub for SAP, and Neptune DXP - Open Edition 24.15 or higher. Neptune Software grants access to the delivery repository during onboarding.

Key capabilities

  • Define APIs in the Hub API Designer of Neptune DXP - Open Edition and test them in the integrated Swagger UI. The API definitions are stored and executed in the SAP S/4HANA Cloud Public Edition tenant.

  • Implement API logic in your own data provider classes in ABAP for Cloud Development, released under contract C1 for use in cloud development.

  • Serve all APIs through one inbound HTTP endpoint. No configuration is needed per API.

  • Expose the endpoint with the delivered communication scenario /NEPTUNE/DXP_CS_INBND and its inbound service /NEPTUNE/DXP_HTTP. You do not create your own communication scenario.

  • Authenticate inbound calls with basic authentication, OAuth 2.0, or client certificates. Principal propagation is recommended for production, so that each call carries the identity of the calling user.

  • Give administrators access in the tenant with the delivered business role template /NEPTUNE/DXP_BRT_ADMIN.

Delivery and lifecycle

  • The add-on is delivered with SAP’s multi-off delivery approach. You install, update, and uninstall it with gCTS from the private GitHub repository neptune-software/dxp-sap-integration-hub-public-s4. abapGit is not supported.

  • The main branch carries the released versions. Releases follow semantic versioning, and the latest released version is actively maintained.

  • Every pull is started by you, at a time of your choosing. Neptune Software never pushes changes into a customer tenant.

  • The add-on is delivered as software component ZPARTNER in the namespaces /NEP/ and /NEPTUNE/. It has a footprint of approximately 15 MB and does not extend any SAP tables.

  • All traffic flows from Neptune DXP - Open Edition into the tenant. The add-on makes no outbound connections.

Known limitations

  • The Hub MCP Designer is not available for SAP S/4HANA Cloud Public Edition.
