How to create a new independent IAS tenant for newly provisioned SAP Cloud ALM tenant?

[SAPSupport]

We were creating a provisioning request for SAP Cloud ALM and everything was o.k.
At the time of selecting the IAS tenant, it didn't let us choose a new, independent one just for SAP Cloud ALM.
Our only option was to select an existing IAS tenant in our landscape to be connected to our SAP Cloud ALM tenant.

We do not want our existing Productive IAS tenant to be shared with SAP Cloud ALM.
How can we create a new IAS tenant, just for our SAP Cloud ALM tenant?

A new Identity Authentication Service (IAS) tenant is created while provisioning SAP Cloud ALM only if no Productive IAS tenant already exists in the Customer landscape.
If a Productive IAS tenant already exists in the Customer landscape, there is no option to create a new IAS tenant during the SAP Cloud ALM provisioning process.
Instead, the provisioning requester must select one of the existing Productive IAS tenants to be linked to SAP Cloud ALM.

If you already have a Productive IAS tenant but wish to create a new one, you must purchase the IAS tenant through the official channels.

Once you have purchased an IAS tenant and configured it, you can connect it to your SAP Cloud ALM tenant via the "Trust Configurations" settings in the Business Technology Platform cockpit Global and Sub accounts for SAP Cloud ALM.
