<a name="capacity-management-editing-capacity-reservations"></a>

After you create a capacity reservation, you can adjust its number of DPUs and add or remove its custom tags.

**To edit a capacity reservation**

1. Open the Athena console at [https://console.aws.amazon.com/athena/](https://console.aws.amazon.com/athena/home).

1. If the console navigation pane is not visible, choose the expansion menu on the left.

1. Choose **Administration**, **Capacity reservations**.

1. In the list of capacity reservations, do one of the following:
   + Select the button next to the reservation, and then choose **Edit**.
   + Choose the reservation link, and then choose **Edit**.

1. For **DPU**, choose or enter the number of data processing units that you want. For more information, see [Understand DPUs](capacity-management.md#capacity-management-understanding-dpus).
**Note**  
You can request to add DPUs to an active capacity reservation at any time.
You can request to decrease DPUs from an active capacity reservation when 1 minute has passed since the reservation became active or when DPUs were last added.
When you request to decrease DPUs, Athena prioritizes removing idle DPUs over active DPUs. If queries are consuming DPUs that are marked for removal, Athena waits for queries to complete before removing the DPUs. 

1. (Optional) For **Tags**, choose **Remove** to remove a tag, or choose **Add new tag** to add a new tag.

1. Choose **Submit**. The details page for the reservation shows the updated configuration.
