   1. When the Administrator is not known, and you need to add an additional Administrator, you first need to visit SAP Cloud Identity Services – Tenants application. This site will allow you to verify that working in the company. To check the IAS tenants who belongs to your company (customer ID) and the corresponding tenant administrators, you will need to login in “SAP Cloud Identity Services – Tenants” application with an S-user who belongs to the same customer ID.
   2. If the Administrator is still working in the company and moved to another department or to a different role, SAP cannot add a new Administrator, the reason for this Is:
      “Due to possible legal issues, SAP adds additional tenant administrators only in exceptional cases (the existing tenant administrator is not available anymore -> example: left the company or there are no any active tenant administrators in tenant). ”The already existing tenant Administrator needs to add additional Administrators.
