+## How can I backfill data after changing my report settings or when a new methodology is released?
+
+Open a support case to request a backfill of your carbon data. In your support case, make sure to provide the report name and the start date for your backfill. For more information on opening a case, see [Getting help with your exports and reports](https://docs.aws.amazon.com/cur/latest/userguide/billing-get-answers.html).
+
+Note that you can't get a backfill of carbon data for the following scenarios:
+
+  * You can't get a backfill for carbon data from before the date that you created the account.
+
+  * If you use AWS Organizations and the structure of your organization changed, such as which account is designated the management account, then you can't get a backfill of data with the previous organization structure.
+
+  * If you use AWS Organizations and you change organizations, then you can't get a backfill of data from prior to joining your current organization
