DataArts Studio assigns permissions through DAYU system roles and workspace roles. To ensure that the IAM user permissions are normal, the user group to which the IAM user belongs must be assigned the DAYU User or DAYU Administrator role on the IAM console. In addition, ensure that the IAM user with the DAYU User role has been assigned the corresponding role in the DataArts Studio workspace.

If you assign only the workspace role to the user, an error message is displayed, indicating that the user does not have permissions. In this case, you need to check whether the user group to which the IAM user belongs has been assigned the DAYU User or DAYU Administrator role on the IAM console. To create an IAM user and assign a system role to the user, perform the following steps:

1. Create a user group and assign permissions to it.

   Log in to the IAM console using a HUAWEI CLOUD account, create a user group, and grant permissions of a common user (for example, DAYU User) to the group.

   For details, see Creating a User Group and Assigning Permissions.

   

   • When configuring DataArts Studio permissions for a user group, enter DAYU in the search box to search for the permissions and select the permissions to be granted to the user group, for example, DAYU User.
   • If an IAM user wants to create a workspace, you must assign the IAM user the DAYU Administrator policy. Users with the DAYU Administrator policy can perform all operations on DataArts Studio.
   • DataArts Studio is a project-level service deployed in specific physical regions. If you select All resources for Scope, the permission takes effect in all projects of all regions. If you select Region-specific projects for Scope, the permission takes effect only for a specified project. When accessing DataArts Studio, the IAM user must switch to the region where they have been assigned the required permissions.

2. Create a user and add the user to the user group.

   Create users on the IAM console and add them to the group created in step 1.
