          }
        ],
        "Version": "1"
      }

2. Add the RAM role as a workspace member.

      In the Batch Assign Roles section, select Development. For more information, see Grant permissions to a RAM user.

3. Grant the RAM role the permissions to manage a MaxCompute table.

   1. On the Workspace page, choose Compute Engine Information > MaxCompute > Go to the MaxCompute Console.

   2. On the MaxCompute project management page, click Role Permissions. If the following error is reported, perform the following operations in the role list: Find the admin role and click Manage Members in the Actions column.

   Command	Description
   USE project-name;	Specifies a MaxCompute project. You must specify the MaxCompute project that you specified when you created a data shipping job of the new version. For more information, see Create a data shipping job of the new version to ship data to MaxCompute.
   ADD USER RAM$****.aliyunid.com:`role/maxcomputeshiprole`;	Adds the RAM role as a user to the MaxCompute project. ****.aliyunid.com specifies the Alibaba Cloud account to which the MaxCompute project belongs. You can run the list users; command to view the Alibaba Cloud account. maxcomputeshiprole specifies the name of the custom RAM role. The name must be in lowercase.
   GRANT DESCRIBE, ALTER, UPDATE ON TABLE table-name to user RAM$****.aliyunid.com:`role/maxcomputeshiprole`;	Grants the RAM role the permissions to view, modify, and update the specified MaxCompute table. Note The authorization procedure applies only to the specified MaxCompute table. If you want to grant the RAM role the permissions to manage all tables in the current MaxCompute project, run the GRANT admin to user RAM$****.aliyunid.com:`role/maxcomputeshiprole`; command to complete the authorization.
   SHOW GRANTS FOR `RAM$****.aliyunid.com:role/maxcomputeshiprole`;	Checks whether the authorization is successful.
