## 3.1 Prerequisites
Prerequisites for Joule Onboarding.
Before completing the Joule onboarding tasks, you'll need to ensure you've met the required prerequisites for both your product and for Joule.
## SAP Product Prerequisites
- You have a license for an SAP product that supports Joule integration (such as SAP SuccessFactors, SAP S/4HANA Cloud Private Edition. etc) in one of the supported data centers, as Joule is an embedded application that is integrated with SAP products. For more information, see Data Centers Supported by Joule.
##  Note
- Joule is available with SAP Start under Early Adopter Care program only.
- If you want to integrate Joule with SAP Start, you must have a license of at least one SAP product that supports Joule integration.
- You have integrated the SAP product with Identity Authentication as Joule leverages the IAS setup of the SAP product for user login.
##  Note
All SAP products that you want to integrate with Joule need to use the very same SAP Cloud Identity services tenant and within all products the same identity (Global User Id) needs to be present.
- You have an enterprise global account on SAP BTP as Joule is an SAP BTP based application and relies on SAP BTP services. For more information, see Enterprise Accounts.
##  Note
If you already have a global account in SAP BTP, Joule entitlements can be added in the same global account.
## Joule Specific Prerequisites
- You have the entitlements for Cloud Identity Services- Identity Authentication and Identity Provisioning. Joule uses the Identity Authentication for user login and Identity Provisioning service to handle provisioning of identities and their authorizations to various business applications (SAP SuccessFactors, Identity Authentication Service Tenant, SAP Build Work Zone, standard edition). For more information, see Tenant Models and licensing information for Identity Authentication and Identity Provisioning.
##  Note
Please contact your account executive if any of the entitlements are not available in your global account.
- To support navigation to different applications from Joule and handle role based access scenarios, you need to configure the navigation service of SAP Build Work Zone. Verify that your global account is configured with the following entitlements. For more information, see Managing Entitlements and Quotas Using the Cockpit.
##  Note
By default SAP Build Work Zone, standard edition uses the SAP Authentication and Trust Management service (XSUAA) for identity authentication. Therefore we recommend that you first switch to
SAP Cloud Identity Services - Identity Authentication as the authentication mechanism. For more information, see Switching to SAP Cloud Identity Services - Identity Authentication.
To get an understanding on services that have mandatory SAP Build Work Zone requirements, see Integrating Your SAP Solution [page 23]. The Joule conversational search capability doesn't require integration with SAP Build Work Zone, standard edition.

##  Note
All SAP BTP Global accounts already include entitlements for the foundation plan of SAP Build Work Zone, standard edition. Joule can only interact with one SAP Build Work Zone instance, therefore it is recommended to install Joule into an existing SAP Build Work Zone instance. If no SAP Build Work Zone instance exists you can start with foundation plan included in your SAP BTP Global account. Make sure that you choose the same plan for SAP Build Work Zone, standard edition for the application and service.
Joule uses the navigation service component of SAP Build Work Zone, standard edition to resolve intent based navigation targets and configure additional content providers. The content needs to be exposed by the SAP product (source system) and consumed by SAP Build Work Zone (target system).
- You have created a subaccount in your global account using the SAP BTP cockpit for provisioning Joule. A single Joule subscription can be integrated into multiple SAP products like SAP SuccessFactors, SAP S/ 4HANA Cloud Private Edition, or SAP Build Work Zone. However, one subscription of the Joule application can only be integrated with one tenant of an SAP product. This means you cannot include multiple systems of the same product in one Joule formation.
You must ensure that there is one IAS tenant per single independent entity and operate every single independent entity from its own dedicated SAP BTP sub-account.

For more information, see Create a Subaccount in the Cloud Foundry Environment.
