## 6b. Select Subaccount
To choose an existing subaccount for this booster, select the relevant subaccount from the list under Subaccount .
Entitlements : Depending on your use case, you can delete optional entitlements of applications that you don't want to subscribe.
You can deselect optional applications in this step under Action .
7. Add additional users as Administrators or Developers. The booster will assign the relevant roles automatically. The user who is configuring the booster is added as administrator and developer automatically.
8. Review the configuration settings you made, especially regarding the subaccount mode. When you are happy with your choices, choose Finish .

The booster will make the settings according to your configuration.
## Step Task
9. When the booster configuration is complete, some settings still have to be made manually, depending on your configuration needs:
- As the booster can only create user interface access for Administrators and Developers, business users have to be added manually. See Enable Authentication and Single Sign-On for Business Users [page 34].
- Define Subaccount Administrators [page 33]
- Configure Your SAP Cloud Identity Services Tenant as Identity Provider or Proxy of Your Subaccount [page 35]
- Build Role Collections [page 35]
- Define Roles to Restrict Authorization by Market (Optional) [page 38]
- Assign Role Collections to Users or User Groups [page 40]
- To enable the integration of SAP Subscription Billing apps with the SAP Fiori launchpad of SAP S/4HANA Cloud Public Edition, follow the procedure described under Integration with the SAP Fiori Launchpad of SAP S/4HANA Cloud Public Edition in the Setup and Administration Guide .
##  Note
API scopes for recently deployed features may not be up to date when you run the booster for the initial onboarding. Missing API scopes need to be added manually. For more information, see Create a Service Instance [page 44].
