Add a custom field with value dependent on the values of another default field

[VT Jira]

I want to add a custom field with a value dependent on the values of another default field.
Example: We have the default fields for estimation like Story points and Original Estimates, Now I want to create a new custom field say QA estimates, this field is 10% of the value of the original estimates. 

I have the admin access for the product.

How I can do that?

Hi @VT Jira 

Welcome to the Atlassian Community!

You can use Automation for Jira for this use case. Since you have admin access, you can take below steps. 

1. Go to Automation:

   • Navigate to Jira Settings > System > Automation rules (or Project settings if you want it at the project level).

2. Create a New Rule:

   • Click on Create Rule.

3. Trigger: Field Value Changed

   • Set the trigger to be when the Original Estimate field changes.
   • Choose Field Value Changed as the trigger.
   • Select Original Estimate as the field to monitor.

4. Condition: Issue Type (Optional)

   • If you only want to apply this rule to specific issue types (like Stories), add a condition to check for the issue type.

5. Action: Edit Issue Fields

   • Add an Action: Edit Issue Fields.
   • Select the custom field you created (e.g., QA Estimates) in the Field drop-down.
   • Set the value to be 10% of the Original Estimate. You can use smart values for this:
     {{issue.timetracking.originalEstimateSeconds}} * 0.1

6. Save and Publish the Rule:

   • Save the rule, name it appropriately (e.g., "Populate QA Estimates"), and turn it on.

Thank you so much @Kishan Sharma , it really helped me a lot. I was able to add the automation.

One more query here:
Like I am adding QA Estimates and PM Estimates (Two custom fields). I also want to create and update a third custom field with the sum of the QA Estimates and PM Estimates. Can we do this using the automation as I was not able to find the exact for this?

I have used {{issue.Story Points}} * 0.15 to update the QA Estimates and PM Estimates fields.

Please suggest.

Hi @VT Jira 

What have you tried already?

Look at how to use automation with smart values on calculations.
