After you have uploaded a CSV data file using the Score Data Uploads page, the file is analysed for errors.
Even if there are no warnings or errors you should use the ‘View report’ button to see the details of what changes will be made to your scores and parts.
If you are happy with the details in the report then you can use the ‘Apply now’ button to apply your CSV data file to your scores. Until you press the ‘Apply now’ button, nothing will be changed.
