SAP S/4HANA

Category: OData · 🏅 Official partner

SAP S/4HANA ERP. Official partner. In Yres, SAP S/4HANA has no dedicated connector with its own form: you connect the system through one of two routes — an OData service via the SAP Gateway (the most common route), or via the SAP Business Data Cloud (SAP_BDC) when data is delivered there as files. A direct database/ODBC connection to the underlying SAP HANA does not exist in Yres (see SAP HANA).

Expected input

Which fields you fill in depends on the route you choose. In every case, the Add source wizard first asks for the shared fields that apply to every source: Source name (unique, 2–45 characters; becomes the name of the linked service and the basis for the Key Vault secrets adf-{bronnaam}-…), type, integration runtime, are credentials identical for all environments?, credentials expiry date and tags.

Route A — OData service (recommended)

In the wizard, choose the source type OData (or OData OAuth if the SAP Gateway uses OAuth). The OData form (getFormAddSourceOdata / getFormAddSourceOdataOauth) asks for:

Field (label)	Notes
Url	The service root of the OData service, in the form https://<host>:<port>/sap/opu/odata/<namespace>/<service_name>/. Yres automatically appends a trailing /.
Pagination type	Fixed at BodyUrl (read-only): pagination uses the OData nextLink.
Body url	JSON path to the next-page link. Defaults to $['@odata.nextLink'].
Authentication type	Anonymous or Basic. With Basic, the extra fields Username and Password appear — the SAP (communication) user with read authorization.
HTTP headers (optional)	One or more header/value pairs for APIs that require an additional header.

For OAuth (via the OData OAuth route), instead of username/password you fill in the OAuth fields: Client id, Client secret, Access token url, Scope and Grant Type (Client Credentials or Authorization Code; with Authorization Code a Refresh token is also required).

• Authentication: Basic (SAP user + password) or OAuth2, depending on how the SAP Gateway is configured.
• Integration runtime: if the OData service is publicly reachable, choose AutoResolveIntegrationRuntime (cloud). If the SAP Gateway is on-premises or behind a firewall, choose a self-hosted integration runtime.
• Secrets: Yres does not store secrets itself. The backend writes the values to the customer's Azure Key Vault under the group adf-{bronnaam}-… (for Basic, among others adf-{bronnaam}-basic-http-username and adf-{bronnaam}-basic-http-password; the URL as adf-{bronnaam}-http-url); the linked service references them.

See the OData and OData OAuth pages for the full field overview of these two source types.

Route B — SAP Business Data Cloud (SAS token)

If data is delivered via SAP BDC as files (Azure Blob FS / Data Lake), you connect it through the SAP_BDC form with a SAS uri, container and SAS token. This is a separate route with its own authentication (SAS) and runs on the cloud integration runtime. See SAP Business Data Cloud for the fields, the validation rules and the fixed delta column ETL_DATE.

No dedicated source type — via SAP_BDC or OData

SAP S/4HANA has no dedicated source type or form in CreateSource.tsx. Depending on the use case, you connect S/4HANA via SAP_BDC or via OData (SAP Gateway). Which route fits depends on how the SAP environment exposes its data; coordinate this with your SAP/Basis administrator. The saphana/saptable images in the webapp are just icons, not separate connectors.

Where to find these

S/4HANA connects most often via an OData service from the SAP Gateway.

• Activate the OData service — A Basis/SAP administrator activates the required OData service in the SAP Gateway. Use transaction /IWFND/MAINT_SERVICE (Service Maintenance) for this: add the service via Add Service, choose the system alias of the back-end system (e.g. LOCAL) and activate the service. Its status must be Active.
• Service URL — The URL has the form https://<host>:<port>/sap/opu/odata/<namespace>/<service_name>. Host and port are those of the SAP Gateway/ICM (often HTTPS port 443 or 5<instance>43). You can test the service with transaction /IWFND/GW_CLIENT.
• Authentication — Basic authentication with an SAP (communication) user, or OAuth if the Gateway is configured for it. The user needs read authorization on the underlying data.

Requirements

• An activated OData service in the SAP Gateway (see above) and an SAP (communication) user with read authorization on the relevant data.
• For OAuth: a configured OAuth client in the SAP Gateway (client id/secret, token endpoint).
• For an on-premises or firewalled SAP environment: an installed and published self-hosted integration runtime that can reach the SAP Gateway.

Load types and delta

S/4HANA via OData supports the standard load types (FULL, DELTA, OVERWRITE, RELOAD, IMAGE, ADDITIONAL). Note: FULL and RELOAD preserve history (SCD2); only OVERWRITE removes the existing history. For delta loads, set a delta column based on a reliable changed-on field in the OData entity.

Official docs: Activate OData Service in the SAP Gateway Hub (SAP Help Portal).
