* After entering the Merge and Review page, the system will check whether the data to be merged has data conflicts. If the data file names are the same, the datasets cannot be merged. If Merge and Verify is successful, you can click **Create Merged Dataset** to enter the creation page. If the step of Merge and Verify fails, please modify it according to the error prompt and try again.
