Rating tables can have one of the following statuses:

> ℹ️ **Note**
> ℹ️ 
> ℹ️ By default, the Rating Tables module displays only *Active* rating tables. You can view *Inactive* or *Retired* rating tables by using the [Search](https://rubiconwater.atlassian.net/wiki/spaces/DCNC/pages/2048721208) tool.

| **Status** | **Description** |
| --- | --- |
| Active | The Active rating table is the one that is used for calculating derived data values from source data collected at the current date and time. |
| Valid but Inactive | These include:<br>- Tables that are still used for historical source data, but that have an **End Date** in the past.
- Rating tables with a **Start Date** in the future. |
| Retired | These are tables whose formula or data points have been corrected, so the original, retired table is no longer used to calculate derived data from source data, whatever the date of the source data.<br>In the list of rating tables in the Rating Tables module, retired rating tables are marked with an asterisk beside the date range. They can also be viewed in the Revisions tab of the rating table that replaced them so that you can trace any corrections made to a rating table. |

## How Rating Tables are Applied

When a derived data point is calculated from a source data point, the rating table used for the calculation is the valid table whose active date range includes the date when the source data point was collected. This means that if you [recalculate](https://rubiconwater.atlassian.net/wiki/spaces/DCNC/pages/2048721228) historical data, the derived data may be calculated from more than one rating table depending on the date range and status of each table.

Retired rating tables are NOT used to calculate derived data.
