## 4.1 Register Your SAP S/4HANA Cloud Public Edition Tenants in Your Global Account
To connect an SAP S/4HANA Cloud Public Edition tenant with a global account in SAP BTP, you need to register the tenant in the corresponding global account.
## Prerequisites
You are an administrator of the global account where you want to register your SAP S/4HANA Cloud Public Edition tenant.
## Context
The registration process is based on a registration token that is used for the pairing of the SAP S/4HANA Cloud tenant and the corresponding global account. You create the token in the global account, and then the tenant
administrator of the respective SAP S/4HANA Cloud tenant uses the token to start the automated registration process on the SAP S/4HANA Cloud tenant side.
##  Note
- When registering SAP S/4HANA Cloud tenants, you can have up to 1000 tokens per global account ready to be used. Tokens that are already used to register an SAP S/4HANA Cloud tenant are not included in this number.
This means that you cannot have more than 1000 tenants on the Systems page of type SAP S/4HANA Cloud with an empty status and generated token that is not used yet.
- You cannot migrate the registered SAP S/4HANA Cloud tenants between global accounts. If you want to start using another global account, you will have to register your SAP S/4HANA Cloud tenants again.
- When registering a tenant or creating a formation, the data you provide in the given input fields is not encrypted with your customer managed key. The data you enter is only encrypted at rest.
## Procedure
1. In the cockpit, navigate to your global account, and then choose System Landscape Systems . The term "system" is used in the cockpit as an overall term for systems and tenants.
2. On the Systems page, choose Add System .
- a. In the Type dropdown list, select SAP S/4HANA Cloud .
- b. Enter a name for the tenant you want to register.
- c. Choose Add .
- d. In the Communication Scenario Groups dropdown menu, select
- Integration with SAP Subscription Billing to enable connectivity between SAP Subscription Billing and SAP S/4HANA Cloud.
- Integration with SAP Master Data Integration to enable connectivity between SAP Subscription Billing and SAP Master Data Integration.
- Eventing Between SAP Cloud Systems to enable connectivity between SAP Subscription Billing and SAP S/4HANA Cloud via SAP Cloud Application Event Hub.

Alternatively, you can select All Communication Scenarios .
- e. Choose Get Token .
The system generates the registration token.
- f. Copy the registration token and send it to the tenant administrator for the respective SAP S/4HANA Cloud tenant. You need it for configuring the integration on the extended SAP S/4HANA Cloud tenant side.
You can also get the registration token later, once the tenant appears in the list on the Systems page.
The registration token is valid for 7 days after it has been generated. When a token is not used within its validity period, it is no longer valid and cannot be used for registering an SAP S/4HANA Cloud tenant. If the validity of the token expires before you use it to configure the integration on the SAP S/4HANA Cloud tenant side and complete the registration, you need to get a new token. You can then copy it and use it to complete the registration.
##  Note
A registration token can be used only once, for registering a single SAP S/4HANA Cloud tenant.
- g. Close the wizard.
The SAP S/4HANA Cloud tenant appears in the list of systems on the Systems page. Its Status field is empty because the registration process is not yet completed.
3. Start the automated registration process on the SAP S/4HANA Cloud tenant side. To do so, proceed as described in as described below under Trigger the Registration in the SAP S/4HANA Cloud Tenant .
##  Note
You can register a tenant with the same name only once per global account. Once you have started a registration process for a tenant with a specified name you can no longer register a tenant with the same name and connect it with the same global account, unless you delete the corresponding extension in the Maintain Extensions on SAP BTP in the SAP S/4HANA Cloud tenant. If the registration process fails, you need to delete the failed extension from the SAP S/4HANA Cloud tenant and create a new integration token in the cockpit for the corresponding tenant to be able to start the automated registration process again.
4. Check the status of the registration process. To do so, in the cockpit navigate to your global account, and on the Systems page, check if the status of the SAP S/4HANA Cloud tenant has changed to Registered .
If you are already on the Systems page, refresh the page to check if the status has changed.
For information about registration statuses and about deregistering systems, refer to the generic SAP BTP documentation Register an SAP S/4HANA Cloud System in a Global Account in SAP BTP.

3. In the Integration Token field, enter the content of the registration token from the SAP BTP cockpit.
4. Choose Save . A new entry appears in the Extensions list with status Enabling .
5. After the integration has finished successfully, you can refresh the list.
The status of the integration should have changed to Enabled .
## Results
Your SAP S/4 HANA Cloud tenant is now registered in your SAP BTP global account.
