Scenario 1：Use a default role to transfer data within the same Alibaba Cloud account
When you use a Resource Access Management (RAM) user to create a data transformation job, you can specify a default role to transfer log data within the same Alibaba Cloud account.
Step 1：Use an Alibaba Cloud account to create the AliyunLogETLRole system role
| Note This step is required for the first time you grant permissions to the AliyunLogETLRole system role.If the system role is granted the required permissions within your Alibaba Cloud account, you can skip this step. |
Log on to the Simple Log Service console by using an Alibaba Cloud account.
Grant permissions to the AliyunLogETLRole system role.
