How do I get fields to autopopulate when I create a linked issue?

[erica_dahl]

For example,  if I create a child issue, I would like some of the custom fields to autopopulate from the epic issue so people don't have to manually re-enter them.

Hi @erica_dahl , thanks for your question. 

I would use an automation for this. 

You can use a rule like this in the automation library as an example / to get some ideas. Basically here, we're creating a series of subtasks and you could copy in the same moment, the values from the custom fields in the parent issue

The other possibility would be to use custom field  contexts and default values. https://support.atlassian.com/jira-cloud-administration/docs/edit-a-custom-field-context/ .

If, for example, in a certain project, the custom field is only used in one issue type and should be populated with a default value, you could set a custom field context for the project / issue type combination and set a default value. For example, if you have a radio button with a yes or no choice, you could set it as a default to yes and then people have to change it to no. 

Anyway, I hope this helps you. Please write again here if you have any questions or doubts. 

Best wishes
