If you have changing SLA durations per issue, you can use this function to set SLA duration dynamically. The SLA clock will count according to this field.

To set an SLA Goal as a Dynamic Duration, you need to create a Dynamic Duration custom field within TTS beforehand. This custom field will appear only in the screens you select while creating the custom field, whether you define the SLA Goal as Dynamic Duration or not.

Here’s how to create a duration custom field:

1. Log in to your Jira Cloud instance.
2. Click on the cog icon to see the **Settings** menu.
3. Go to **Issues** under **Jira Settings**.
4. Click **Custom Field** in the left column to see the Custom Fields menu.
5. Click **Create Custom Field**, and a** **screen will pop up.
6. Select **Text field** (single line).
7. Create a **Name **for the duration field.
8. Click **Create.**
9. You’ll be redirected to the **Associate field SLA Duration** screen.
10. Tick the screens on which you want the duration field to appear. **Remember**: The field will **only** be in the screens that you selected!
11. Click **Update**.

Now, you can see the** Duration Field **in the Dynamic Duration drop-down menu whilst defining or updating an SLA.

> 📝 Afterward, you can change your screen settings by going to the **Custom Fields** menu and clicking **... icon** > **Associate to Screens** in the row of the** Duration Field** that you want the screens to be displayed on. On the Associate Field to Screens page, make the changes and click **Update**.
