CUR report name to backfill

To backfill data for your CID (Cost Intelligence Dashboard) dashboards, you should provide the report name for the Cost and Usage Report 2.0 (CUR 2.0) export. Based on the information you've provided, the correct report name to give for backfilling would be "cid-cur2".

The reason for choosing this report is that CUR 2.0 is the primary source for detailed billing and cost management data in AWS Data Exports. It contains comprehensive information about your AWS usage, including resource-level details, pricing, and cost allocation tags.

The other two exports you mentioned serve different purposes:

1. "cid-coh" likely refers to Cost Optimization Hub recommendations, which provides suggestions for cost savings but doesn't contain historical usage data.
2. "cid-focus" probably relates to FOCUS 1.0 with AWS columns, which is a different data set and not the primary source for backfilling historical cost and usage data.

When you request a backfill through AWS Support, they will populate your CUR 2.0 report with historical data, maintaining the same structure and level of detail as your current CUR 2.0 export. This will ensure that your Cost Intelligence Dashboard has consistent and complete historical data for analysis.
