##  Note
The SAP SuccessFactors Extensibility service is also availаble for global accounts marked with EU Access. See Regions.
SAP BTP offers a standard way for extending SAP solutions.
You can extend SAP SuccessFactors systems without disrupting the performance and the core processes. When building extension applications, you can also benefit from the automation of the integration between the cloud platform and SAP SuccessFactors.

| 1. Connect the SAP SuccessFactors system that you want to extend with the corresponding global account in SAP BTP.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   | Register an SAP SuccessFactors System in a Global Account in SAP BTP [page 2061].                                                                                                                                |
| During the pairing process you create a registra- tion token which is then used by the SAP Suc- cessFactors system tenant administrator to con- figure the integration on the SAP SuccessFactors system side.                                                                                                                                                                                                                                                                                                                                                                                                                        |  Note You cannot migrate the registered SAP SuccessFactors systems between global accounts. If you want to start using another global account, you will have to register your SAP SuccessFactors systems again. |
| 2. Make the SAP SuccessFactors system accessi- ble in the subaccounts in which you want to build your extension applications. To do so, you configure the entitlements and as- sign the corresponding quota where the extension applications will reside.                                                                                                                                                                                                                                                                                                                                                                            | Configure the Entitlements for the SAP SuccessFactors Extensibility Service [page 2179]                                                                                                                          |
| 3. Configure the communication flow. To do so, create a service instance of the SAP SuccessFactors Extensibility service using the api-access service plan. During the service instance creation an HTTP des- tination on a subaccount level is automatically generated in this subaccount. It contains all in- stance binding properties which are sufficient to establish connection to the SAP SuccessFactors system. SAP BTP supports the following authentication scenarios for SAP SuccessFactors: • OData access with OAuth 2.0 SAML bearer assertion • OData access with OAuth 2.0 SAML bearer assertion with technical user | Create a Service Instance to Consume the SAP SuccessFactorsHXM Suite OData API [page 2180]                                                                                                                       |

| 4. Configure the Single-Sign On (SSO) between the subaccount in SAP BTP and the SAP Success- Factors system. To ensure the required security for accessing the applications, you need to configure the single sign-on between the subaccount in SAP BTP and the SAP SuccessFactors system using a SAML identity provider.   | Configure Single Sign-On Between a Subaccount in SAP BTP and SAP SuccessFactors [page 2187]   |

If you have performed an automated instance refresh or your cloud operators have performed a manual instance refresh, you need to restore some of the extension configuration settings.                                                                                                                                  | Restore Configuration Settings After an Instance Refresh [page 2192]                          |
