# Configuring Cost and Usage Reports using Billing Conductor
<a name="cur-data-view"></a>

You can create pro forma AWS Cost and Usage Reports (AWS CUR) for each billing group that you create in Billing Conductor. The pro forma AWS CUR has the same file format, granularity, and columns as the standard AWS CUR. Pro forma contains the most comprehensive set of cost and usage data available for a given period of time. For more information about Billing Conductor, see the [https://docs.aws.amazon.com/billingconductor/latest/userguide/what-is-billingconductor.html](https://docs.aws.amazon.com/billingconductor/latest/userguide/what-is-billingconductor.html).

## Understanding the differences between Billing Conductor AWS CUR and standard AWS CUR
<a name="cur-abc-type-differences"></a>

There are a few differences between the standard Cost and Usage Reports and pro forma AWS CUR created using the Billing Conductor configuration.
+ The standard AWS CUR computes the cost and usage for each account in your consolidated billing family. A pro forma AWS CUR per billing group only includes the accounts in the billing group at the time of computation.
+ The standard AWS CUR populates the invoice column once and invoice is generated by AWS. A pro forma AWS CUR doesn't populate the invoice column. Currently, no invoice is generated, or issued by AWS based on pro forma billing data.

## Create pro forma Cost and Usage Reports for a billing group
<a name="create-proforma"></a>

Use the following steps to generate a pro forma AWS CUR for a billing group.

**Note**  
The legacy AWS Cost and Usage Report page supports reports only for billing group views. To create reports for billing transfer views, use the Data Export page.

**To create pro forma Cost and Usage Reports for a billing group**

1. Open the Billing and Cost Management console at [https://console.aws.amazon.com/costmanagement/](https://console.aws.amazon.com/costmanagement/).

1. In the navigation pane, under **Legacy Pages**, choose **Cost and Usage Reports**.

1. On the top right of the **Report table**, choose **Settings**.

1. Turn on the **Pro forma** data view.

1. Choose **Enable**.

1. Choose **Create report**.

1. For **Report name**, enter a name for your report.

1. For **Data view**, choose **pro forma**.

1. Choose a billing group.

1. For **Additional report details**, choose **Include resource IDs** to include the IDs of each individual resources in the report.

1. For **Data refresh settings**, choose if you want Cost and Usage Reports to refresh if AWS applies refunds, credits, or support fees to your account after finalizing your bill. When a report refreshes, a new report is uploaded to Amazon S3.

1. Choose **Next**.

1. For **S3 bucket**, choose **Configure**.

1. In the **Configure S3 Bucket** dialog box, do one of the following:
   + Choose an existing bucket from the drop down list and choose **Next**.
   + Enter a bucket name and the AWS Region where you want to create a new bucket and choose **Next**.

1. Review the bucket policy, select **I have confirmed that this policy is correct**, and choose **Save**.

1. For **Report path prefix**, enter the report path prefix that you want prepended to the name of your report.

   This step is optional for Amazon Redshift or Quick, but required for Amazon Athena. If you don't specify a prefix, the default prefix is the name that you specified for the report in step 7, and the date range for the report in the following format: `/report-name/date-range/` 

1. For **Time granularity**, choose one of the following:
   + **Hourly** if you want the line items in the report to be aggregated by the hour.
   + **Daily** if you want the line items in the report to be aggregated by the day.

1. For **Report versioning**, choose whether you want each version of the report to overwrite the previous version of the report, or to be delivered in addition to the previous versions.

   Overwriting reports can save on Amazon S3 storage costs. Delivering new report versions can improve auditability of billing data over time.

1. For **Report data integration**, choose whether you want to upload your Cost and Usage Reports to Amazon Athena, Amazon Redshift, or Quick. The report is compressed in the following formats:
   + **Athena**: parquet format
   + **Amazon Redshift or Quick**: .gz compression

1. Choose **Next**.

1. After you have reviewed the settings for your report, choose **Review and Complete**.
