Hello @Esra Gümüskaya
Thank you for reaching out. I would like to confirm following:
- Account Administrator, Service Administrator, and Co-Administrator are the three classic subscription administrator roles in Azure. Classic subscription administrators have full access to the Azure subscription. They can manage resources using the Azure portal, Azure Resource Manager APIs, and the classic deployment model APIs.
- For more information, please review following document: Classic subscription administrator roles
As per your requirement we would recommend you to assign RBAC Owner/Contributor Access to user on Resource Group or Child Resource scope. For steps to assign RBAC role to a user please review following documentation: Assign Azure roles using the Azure portal.
I hope this helps you achieve the results you are looking for.
