SAP HANA Cloud subscription failing in new BTP subaccount — OIDC trust error / IAS not configured #323

Issue description

Component: HAN-CLS-HC

Description:

We are unable to subscribe to SAP HANA Cloud in our new BTP subaccount. The same subscription worked previously in an older subaccount.

What changed: In the old subaccount, the Service Marketplace showed two separate tiles: hana-cloud and hana-cloud-tools. In the new subaccount, only hana-cloud-tools-ias is shown — which now requires an IAS (Identity Authentication Service) tenant configured with OIDC trust.

Problem: We do not have an IAS tenant configured in this subaccount. Our product (SAP Business ByDesign) does not use a separate IAS tenant, so there is no IAS trust to establish.

Questions:

Is it possible to subscribe to HANA Cloud without an IAS tenant (using the older flow with hana-cloud + hana-cloud-tools tiles)?
If IAS is now mandatory, how do we get an IAS tenant provisioned for a BTP account linked to SAP Business ByDesign?
Is there a workaround for BTP accounts on the cf-eu12 landscape without an existing IAS tenant?
